[4] CURSIVE HANDWRITING SEGMENTATION AND RECOGNITION

PROJECT GROUP: PAYAL SHAH, ABHINEET SARKAR, PRAMOD MISHRA, RAVIKIRAN NANDE

GUIDE: DR.S.T. GANDHE

Abstract: The off-line cursive handwritten word recognition is a software algorithm implemented using neural network tool box in matlab. With the help of this algorithm the input handwritten image is segmented into characters.  In the task of handwriting recognition, the letters which are interconnected are separated using histogram based image segmentation technique. For this, we need to detect the top end and bottom end of the character. Each letter is thus saved as an image and then given to the neural network, which is trained with sufficient number of pairs of input and output samples of all the 26 characters a training set is made. The algorithm used for neural network training is the back propagation algorithm. The final output of the system is the recognized text which can be further processed on a word application.

[5] AUTOMATED DRIVER FATIGUE DETECTION SYSTEM

PROJECT GROUP: APEKSHA SHENOY, KIRTI KHOPKAR, RUCHIR KANAKIA

GUIDE: PROF.K.T. TALELE

Abstract: A vision-based real-time driver fatigue detection system is proposed for increase in driver safety. Driver fatigue is evaluated on the basis of two parameters: rate of eye closure and yawning. Images of the driver are taken through a camera. Each individual image is checked for the face, eyes and the mouth. If they do not comply with the rules set for fatigue detection then, there is an immediate warning given in the form of an alarm. The system is tested on a hardware platform consisting of a TI OMAP 3530 chip along with other supporting peripherals. The experimental results obtained so far show great promise in the near future. The system can reach 20 frames per second for eye tracking. Efficiency of the system is near 90% in standard light conditions. However, the system may give erroneous results when the illumination level goes low.

[6] OBJECT CLASS RECOGNITION

PROJECT GROUP: SAIKALASH SHETTY, SANTOSH TELANG

GUIDE: PROF.K. T. TALELE

Abstract: We present a method to aggregate certain features in a particular class/group of objects into sort of a dictionary. Then they are compared to the image given by the user to be recognized. The recognition of an object requires detection first. The invariant features once extracted become the reference for the input image detection. After this, the image descriptor is used for classification and then consequent recognition. Stable local feature detection and representation is a fundamental component of many image registration and object recognition algorithms. The SIFT algorithm as being the most resistant to common image deformations. A general trainable system for object detection in static images has been proposed that examines (and improves upon) the local image descriptor used by SIFT.
Like IFT, our descriptors encode the salient aspects of the image gradient in the feature points neighborhood; however, instead of using SIFT smoothed weighted histograms, we apply Principal Components Analysis (PCA) to the normalized gradient patch. The PCA based local descriptors are more distinctive, more robust to image deformations, and more compact than the standard SIFT representation. Normalization and scaling is inherently done. This system can be applied to face, people, car, objects like cycles, bikes for road systems; and aero planes, ammunition, for security; retrieval for image mining of databases, etc.

[7] SPEECH RECOGNITION BASED MOTION TRACKER

PROJECT GROUP: PRASHANTH NAYAK, DIPAL MODI, RAJU PATEL

GUIDE: PROF.K.T.TALALE

Abstract: The objective of the project is to design a speech operated motion tracker for detection of motion. Our tracker is an essential requirement of any surveillance system. Nowadays CCTV cameras are used for security purposes. These cameras can even track the object that is in motion but as they are fixed at a particular place. In this work we present an operational computer vision system for real-time detection and tracking of object in motion. The system captures video of a scene and identifies moving objects using wavelet segmentations, operated by Speaker through speech. We have implemented speech recognition using Wavelet Decomposed LPC which gives 80 percent accuracy. Using Wavelet segmentation we were able to detect motion even in varying brightness, this gives an advantage of tracking motion in the regions of low brightness. Motion tracker can be used in surveillance areas where the CCTV cameras fail, Motion tracker will be able to follow the object until a clear image of the object is retrieved.

PROJECT GROUP: SANKET MORE, SATISH PARATE, HARSHALA MASUREKAR

GUIDE: DR.Y.S.RAO

Abstract: Biomedical Engineering is the application of engineering principles and techniques to the Medical field. This field seeks to close the gap between engineering and medicine. The
Biomedical devices available today only handle single discrete parameter at a time. They do not measure blood pressure, body temperature, pulse rate etc. at a time. Hence they are efficient in measuring single parameter but not ultimate enough to deal with many body parameters. Our project on ‘Real Time Data Acquisition System for Biomedical Application’ deals with the biomedical parameters determined from blood, heart pulses and temperature. It senses these parameters and analyzes it mathematically to have logical and reliable output at the display. It is a multichannel system which eliminates the need of using discrete devices for measuring biomedical parameters. Every channel senses different parameter and gives the corresponding result to the display. The microcontroller decides which channel to select for the output at display in automatic mode and manual mode. It gives preference to the user to select which parameter to be displayed on the LCD. The system also has alarming facility to inform user about the serious need of medicine intake, if the parameter exceeds the range or goes below average. The system can be used as a personal check-up kit and continuous monitoring system in ICU. The system would also beneficial in fields of sports, fitness clubs, and military and other security forces.

PROJECT GROUP: KAUSHIK GURAV, APURVA LIMAYE, ISHAAN KAUL

GUIDE: PROF. M.M. PARMAR

Abstract: Based on high speed ARM processor (ARM 7), a near infrared spectrum based processing and display system was developed. As an innovative method of tissue oxygenation measurement with the NIR spectrum, the system could compute real-time values of various tissue parameters especially oxy-hemoglobin and de-oxyhemoglobin.  With the use of embedded systems, the miniaturization of the system was attempted to make it more portable and user friendly. A detailed analysis of the tissue oxygenation measurement is described.
The instrument design allows the collection of optical data making use of simple electronic components and an efficient circuit and the signal output is displayed as oxy-hemoglobin and de-oxyhemoglobin concentrations ([HbO2], [HHb]) in the blood. To calculate oxy and de-oxy hemoglobin concentration, Modified Beer Lambert law was used. The use of ARM7 based processor is stressed since ARM processor supports real time solutions and multi-tasking. Thus, this application could be merged with many other bio-medical applications in the future. After testing on volunteers and initial gathering of data, the experiment results imply that the equipment is not only user-friendly but also efficient and accurate.
This system based on embedded structure could be applied broadly in the determination of tissue parameters without invading the body. This system could also prove to be useful in diagnosis of breast cancers and brain tumor.

GUIDE: PROF.M.M. PARMAR

Abstract: Our project Vehicle Tracking System is a standalone system which helps display the co-ordinates of a vehicle on a remote PC loaded with internet. When the stand alone system is armed and loaded, the location of a vehicle can be tracked by sending vehicle coordinates through a two-way paging link or a cellular telecommunications link to a base station. The stand alone system continuously transmits the co-ordinates of the vehicle through the internet using GPRS connection on to a remote server and the latitude, longitude co-ordinates can be accessed.
Briefly, the vehicle tracking system includes a receiver transmitter subsystem, a GPS subsystem for locating a position and a control CPU. The CPU performs a log and locates function in which it logs the position of the vehicle and transmits it to a remote server. This operation is continued again and again as long as the stand alone system is supplied power.

Our objective is to successively move a Cartesian coordinate robot as per the given set of motions and to get the end effector at the desired destination through an assembly program and a GUI.

[15] DIGITAL AUDIO WATERMARKING SYSTEM

PROJECT GROUP: NARESH UNIYAL, SHREYA SHETE, NIKHIL DHOOT

GUIDE: PROF.N.A. BHAGAT

Abstract: Digital audio watermarking system is a technique for embedding additional data along with audio signal. Embedded data is used for copyright owner identification. A number of audio watermarking techniques are proposed. These techniques exploit different ways in order to embed a robust watermark and to maintain the original audio signal fidelity. This paper makes a tutorial in general digital watermarking principles and focus on describing digital audio watermarking techniques. These techniques are classified according to the domain where the watermark is embedded. A novel scheme that is able to merge digital watermarking and content authentication of digital audio is presented in this report. The embedding of additional data is performed in different signal domains. Watermark embedding is made by frequency hopping method in the Fourier domain, while the additional authentication data is hidden using the LSB modulation in the wavelet domain. The perceptual transparency is achieved using the frequency masking property of the HAS. The scheme obtains high robustness against standard watermark attacks and localizes accurately tampered parts of the audio clip.

[20] VIRTUAL INSTRUMENTATION USING LABVIEW

PROJECT GROUP: SHWETA U. SHETTY, SHILPA SREEKRISHNAN, SHREELAXMI GOVINDAN

GUIDE: PROF.P.V. KASAMBE

Abstract: The report gives information about the implementation of a PC based virtual instrument (VI) for the experimental setup of a DC motor. Using the VI, the setup can be virtually and remotely controlled. The proposed VI is based on the LabVIEW (Laboratory Virtual Instrument Engineering Workbench) language under the workbench of Windows XP.
Reading inputs, graphically representing data and manipulating the circuitry through the software itself, all in real time, makes this application of a virtual laboratory extremely efficient and a very desirable need of our time. The real time inputs (voltage and current) are taken from the external circuit with the help of the analog channels on the NI ELVIS kit and the DAQ (Data Acquisition Card PCI-6251). These devices are used with LabVIEW to take input from the external circuit.
This can be extended to implementing various laboratory experiments virtually, along with their records, establishing a virtual laboratory and making experiments very simple to perform. It reduces large chunks of workload and hardware to make the system more efficient both with respect to time and accuracy.
