Also we had a limited amount of time for its completion so we were under a certain amount of pressure as well. We had to start from the research phase at the beginning and needed to gain knowledge on all the devices and components that we had intended to use for our project. Other phases of the project included coding, debugging, testing, documentation and implementation and it needed certain time for completion so we really had to manage the limited time available to us and work accordingly to finish the project within the schedule.
Constraints Considerations The following is a list of constraint considerations: This system is only capable of controlling electrical devices. This will help in in- creasing the reliability of the system.
The coding for the project is done using Matlab Matlab is a tool for doing numerical computa- tions with matrices and vectors. It is very powerful and easy to use. In fact, it integrates computation, visualization and programming all together in an easy-to-use environment and can be used on almost all the platforms: In our previous three year of B.
E, of all the programming languages we had obtained the most profi- ciency in Matlab. Hence it was no surprise that we decided to do the project using Matlab. However Matlab has some serious limitations. The processing capacities required by Matlab are very high. Also there are some problems with speed in real time processing.
Matlab is capable of processing only frames per second. On a system with a low RAM this is even lower. As we all know an eye blink is a matter of milliseconds. Also drivers may move their heads rapidly. In particular, the final prototype costs approximately in off the shelf materials with largel-scale production costs likely to fall below While our final prototype was able to reach accuracy rates up to 80 percent, by adjusting the testing procedures and environment and indoor lighting conditions, we are confi- dent that our device will be able to acccurate to about 90 percent.
In particular, the following questions must be asked and thought over for the devices: Fol- lowing this procedure would dramatically reduce part count, improve assembly times and improve the serviceability of the device.
When the plug is inserted and the circuit is complete, the green LED goes on. When the driver is drowsy, the motor slows down and the current in red LED goes down thus mak- ing it glow faintly.
Running the program requires installation of Matlab or higher version of the software installed on yhe computer system.
Also program was produced on a computer having Windows XP. It will run on Windows higher operating systems such as Windows 7, but may require a seperate RS USB-serial connector port and driver. The complete projects divided in different interfacing Parts: Main micro controller unite, use as CPU 2. RS Interfacing 3. Buzzer and DC motor Output Section 4. The crystal oscillator is an electronic circuit that uses the mechanical resonance of a vibrating crystal of piezoelectric material to create an electrical signal with a very precise frequency.
Because of the excellent IO capabil- ities of the PIC micro controller range of devices, and the adoption of TTL levels on most modern PC serial ports, a line drive is often unnecessary unless long distances are involved between the transmitter and the receiver.
The buzzer requires 12 volts at a current of around ma, which can not provided by the micro controller. So the driver transistor is added.
Normally the buzzer remains off. As soon as pin of the micro controller goes high, the buzzer operates. It requires a current of some more than mA, which also cannot be provided by th Microcontroller. This is fed to bridge rectifier, the output of which is then filtered using uf electrolytic capacitor and fed to voltage regulator. LED 2 and its associate 1K current limiting resistors provide power indication. The unregulated voltage of approximately 12V is required for motor and, buzzer driving circuit 5.
Basic Image Processing Using MATLAB
Table 5. Features of 16F72 No.
Component Specification 1 Resistor 3 nos. IN 10 Diode 5 nos. However the throughput, the memory capacity isnt big.
The clock frequency is related with the speed to read the program and to execute the instruction. Only at the clock frequency, the throughput cannot be judged.
It changes with the architecture in the processing parts for same architecture; the one with the higher clock frequency is higher about the throughput. Input voltage levels are compatible with standard MOS levels.
Supply voltage range from 2. Output current 24 mA. Figure 5. The LM is three terminal positive regulator available with several fixed output voltages, making them useful in a wide range of ap- plications.
Each type employs internal current limiting, thermal shut down and safe operation. If adequate heat sinking is provided, they can deliver over 1A output current. The standards are kbps or less and line lengths are 15M 50 ft or less but today we see high speed ports on our home PC running very high speeds and with high quality cable maximum distance has increased greatly.
The rule of thumb for the length a data cable depends on speed of the data, quality of the cable. An RS port can supply only limited power to another device. The number of output lines, the type of interface driver IC, and the state of the output lines are important considerations.
Data is transmitted and received on pins 2 and 3 respectively. This friction opposes the flow of electrons and thus reduces the voltage pressure placed on other electronic components by re- stricting the amount of current that can pass through it.
A capacitor stores electrical energy when charged by a DC source. It can pass alternating current AC , but blocks direct current DC except for a very short charging current, called transient cur- rent. Ceramic and Electrolytic capacitors are used for filtering purposes in the circuit. The basic function of a diode is to allow current to flow in only one direction thus preventing devices from back emf while transistor is best described as a device that uses a small amount of current to control a large amount of current Current Amplifier.
Hence, transistors are used in circuit to drive high power motor and buzzer sections. Circuit Diagram 5. Modern electronic system would be virtually impossible to package without incorporating circuit into their design.
They allow users to make changes and view the working of the current circuit without actually implementing it on board. We have used PCB Wizard software for designing the pcb layout. While designing a layout the size of the board should be kept as small as possible wihtout affecting the perfomance. This can be done manually in yhe PCB Wizard or you may configure it to set a size for the pcb. The layout is generated by forming a circuit by adding components and joining them with the help of wires on the screen.
The PCB Wizard contains a wide range of components in its library, so there should be no difficulty in completing the circuit. Once the circuit is completed, the rest of the process is automated. The Wizard automatically performs routing operation for our circuit as illustrated below: A few PCBs are made by adding traces to the bare substrate or a substrate with a very thin layer of copper usually by a complex process of multiple electroplating steps.
There are many ways of removing the unwanted copper from pcbs and th choice is dependent on the maker. For our project, when the layout was done, the board layers were printed onto special toner transfer paper with a laser printer. After laminating, the board with the paper stuck to it was soaked to remove the paper, leaving only the toner behind.
After etching, the toner was removed with solvent and the board was tinned using a soldering iron and a small piece of tinned solder wick. Drilling Holes, or vies, through the PCB have been drilled with tiny drill bits made of solid tungsten carbide. The drilling was performed by automated drilling machines with placement controlled by a drill tape or drill file.
When very small vies are required, drilling with mechanical bits is costly because of high rates of wear and breakage. In this case, the vies may be evaporated by lasers. Laser-drilled vies typically have an inferior surface finish inside the hole. These holes are called micro vies. Layout of the PCB Soldering For soldering of components, first the terminal to be soldered were cleared to remove oxide film or dirt on it.
Flux was applied as per requirement on the points to be soldered. The joint to be soldered is heated and fixed with the help of soldering iron and soldering wire which has a very low melting point. Heat applied should be such that when solder wire is touched to joint, it must melt quickly.
The joint and the soldering iron is held such that molten solder should flow smoothly over the joint. When the joint is completely covered with molten solder, the soldering iron is removed. Automatic segmentation of fetal brain using diffusion-weighted Imaging cues Abstract: Segmentation of the developing cortical plate from MRI data of the post-mortem fetal brain is highly challenging due to partial volume effects, low contrast, and heterogeneous maturation caused by ongoing myelination processes.
We present a new atlas-free method that segments the inner and outer boundaries of the cortical plate in fetal brains by exploiting diffusion-weighted imaging cues and using a cortical thickness constraint. The accuracy of the segmentation algorithm is demonstrated by application to fetal sheep brain MRI data, and is shown to produce results comparable to manual segmentation and more accurate than semi-automatic segmentation.
Automatic Skin Lesion Segmentation Using Deep Fully Convolutional Networks with Jaccard Distance Abstract: Automatic skin lesion segmentation in dermoscopic images is a challenging task due to the low contrast between lesion and the surrounding skin, the irregular and fuzzy lesion borders, the existence of various artifacts, and various imaging acquisition conditions.
In this paper, we present a fully automatic method for skin lesion segmentation by leveraging layer deep convolutional neural networks that is trained end-to-end and does not rely on prior knowledge of the data. We propose a set of strategies to ensure effective and efficient learning with limited training data.
Furthermore, we design a novel loss function based on Jaccard distance to eliminate the need of sample re-weighting, a typical procedure when using cross entropy as the loss function for image segmentation due to the strong imbalance between the number of foreground and background pixels.
We evaluated the effectiveness, efficiency, as well as the generalization capability of the proposed framework on two publicly available databases. Experimental results showed that the proposed method outperformed other state-of-the-art algorithms on these two databases. Our method is general enough and only needs minimum pre- and post-processing, which allows its adoption in a variety of medical image segmentation tasks.

Bottom-Up Merging Segmentation for Color Images With Complex Areas Abstract: Most color images obtained from the real world usually contain complex areas, such as nature scene images, remote sensing images, and medical images. All these type of images are very difficult to be separated accurately and automatically for complex color and structures included.
In this paper, we focus on detecting hybrid cues of color image to segment complex scene in a bottom-up framework. The main idea of the proposed segmentation method is based on a two-step procedure: 1 a reasonable superpixels computing method is conducted and 2 a Mumford-Shah M-S optimal merging model is proposed for presegment suerpixels. First, a set of seed pixels is positioned at the lowest texture energy map computed from structure tensor diffusion features.
Next, we implement a growing procedure to extract superpixels from selected seed pixels with color and texture cues. After that, a color-texture histograms feature is defined to measure similarity between regions, and an M-S optimal merging process is executed by comparing the similarity of adjacent regions with standard deviation constraints to get final segmentation. Extensive experiments are conducted on the Berkeley segmentation database, some remote sensing images, and medical images.
The results of experiments have verified that the segmentation effectiveness of the proposed method in segmenting complex scenes and indicated that it is more robust and accurate than conventional methods. Detection and segmentation of small renal masses in contrast enhanced Ct images using texture and context feature classification Abstract: Detection and segmentation of small renal mass SRM in renal CT images are important pre-processing for computer-aided diagnosis of renal cancer.
However, the task is known to be challenging due to its variety of size, shape, and location. In this paper, we propose an automated method for detecting and segmenting SRM in contrast-enhanced CT images using texture and context feature classification.
First, kidney ROIs are determined by intensity and location thresholding. Second, mass candidates are extracted by intensity and location thresholding. Third, false positive reduction is applied with patch-based texture and context feature classification. Finally, mass segmentation is performed, using the detection results as a seed, with region growing, active contours, and outlier removal with size and shape criteria.
FitBeat: A Lightweight System for Accurate Heart Rate Measurement during Exercise Abstract: Tracking heart rate for fitness using wrist-type wearables is challenging, because of the significant noise caused by intensive wrist movements. In this paper, we present FitBeat - a lightweight system that enables accurate heart rate tracking on wrist-type wearables during intensive exercises.
Unlike existing approaches that rely on computation- intensive signal processing, FitBeat integrates and augments standard filter and spectral analysis tool, which achieves comparable accuracy while significantly reducing computational overhead. FitBeat integrates contact sensing, motion sensing and simple spectral analysis algorithms to suppress various error sources.
We implement FitBeat on a COTS smartwatch, and evaluate the performance of FitBeat for typical workouts of different intensities, including walking, running and riding. Experimental results involving 10 subjects show that the average error of FitBeat is around 4 beats per minute, which improves heart rate accuracy of the default heart rate tracker of Moto by 10x.
Residual Deconvolutional Networks for Brain Electron Microscopy Image Segmentation Abstract: Accurate reconstruction of anatomical connections between neurons in the brain using electron microscopy EM images is considered to be the gold standard for circuit mapping.
A key step in obtaining the reconstruction is the ability to automatically segment neurons with a precision close to human-level performance. Despite the recent technical advances in EM image segmentation, most of them rely on hand-crafted features to some extent that are specific to the data, limiting their ability to generalize.
Here, we propose a simple yet powerful technique for EM image segmentation that is trained end-to-end and does not rely on prior knowledge of the data. Our proposed residual deconvolutional network consists of two information pathways that capture full-resolution features and contextual information, respectively. We showed that the proposed model is very effective in achieving the conflicting goals in dense output prediction; namely preserving full-resolution predictions and including sufficient contextual information.
We applied our method to the ongoing open challenge of 3D neurite segmentation in EM images.
Our method achieved one of the top results on this open challenge. We demonstrated the generality of our technique by evaluating it on the 2D neurite segmentation challenge dataset where consistently high performance was obtained. We thus expect our method to generalize well to other dense output prediction problems. Segmenting multi-source images using Hidden Markov fields with copula-based multivariate Abstract: Nowadays, multi-source image acquisition attracts an increasing interest in many fields, such as multi-modal medical image segmentation.
Such acquisition aims at considering complementary information to perform image segmentation, since the same scene has been observed by various types of images. However, strong dependence often exists between multi-source images. This dependence should be taken into account when we try to extract joint information for precisely making a decision.
In order to statistically model this dependence between multiple sources, we propose a novel multi-source fusion method based on the Gaussian copula. The proposed fusion model is integrated in a statistical framework with the hidden Markov field inference in order to delineate a target volume from multi-source images. Estimation of parameters of the models and segmentation of the images are jointly performed by an iterative algorithm based on Gibbs sampling.

Experiments are performed on multi-sequence MRI to segment tumors. The results show that the proposed method based on the Gaussian copula is effective to accomplish multi-source image segmentation.
Tumor cell load and heterogeneity estimation from diffusion-weighted MRI calibrated with Abstract: Diffusion-weighted magnetic resonance imaging DWI is a key non-invasive imaging technique for cancer diagnosis and tumor treatment assessment, reflecting Brownian movement of water molecules in tissues. Since densely packed cells restrict molecule mobility, tumor tissues produce usually higher signal a.
However, no general quantitative relation between DWI data and the cell density has been established. In order to link low-resolution clinical cross-sectional data with high-resolution histological information, we developed an image processing and analysis chain, which was used to study the correlation between the diffusion coefficient D value estimated from DWI and tumor cellularity from serial histological slides of a resected non-small cell lung cancer NSCLC tumor.
Color deconvolution followed by cell nuclei segmentation was performed on digitized histological images to determine local and cell-type specific 2d two-dimensional densities. From these the 3d three-dimensional cell density was inferred by a model-based sampling technique, which is necessary for the calculation of local and global 3d tumor cell count.
Next, DWI sequence information was overlaid with high-resolution CT data and the resected histology using prominent anatomical hallmarks for co-registration of histology tissue blocks and non-invasive imaging modalities' data. The integration of cell numbers information and DWI data derived from different tumor areas revealed a clear negative correlation between cell density and D value. Importantly, spatial tumor cell density can be calculated based on DWI data.
In summary, our results demonstrate that tumor cell count and heterogeneity can be predicted from DWI data, which may open new opportunities for personalized diagnosis and therapy optimization. Tumour Ellipsification in Ultrasound Images for Treatment Prediction in Breast Cancer Abstract: Recent advances in using quantitative ultrasound QUS methods have provided a promising framework to non-invasively and inexpensively monitor or predict the effectiveness of therapeutic cancer responses.Moreover, as another contribution, a large and challenging road centerline data set for the VHR remote sensing image will be publicly available for further studies.
Project Time Line No. Flux was applied as per requirement on the points to be soldered. Fol- lowing this procedure would dramatically reduce part count, improve assembly times and improve the serviceability of the device.
Our proposed residual deconvolutional network consists of two information pathways that capture full-resolution features and contextual information, respectively. The research could lead to the development of monitoring and warning systems for drowsy drivers. As we all know an eye blink is a matter of milliseconds.
