  • Modeling the simple and complex cells in visual cortex area 1 and 2 (v1, v2) for Form detection Guide: Dr. Atanendu Sekhar Mandal, Scientist - F, Central Electronics Engineering Research Institute, Pilani, INDIA. Simple cells in visual cortex area 1 and 2 (V1)  are known for their orientation selectivity and orientation tuning. The complex cells on the other hand respond well to at least some of the complex stimuli and explicitly represent complex shape information and suggest specific types of higher order visual information that V2 cells extract from visual scenes. In this work, mathematical models for simple and complex cells are presented. Using these models, a frame work for form detection was presented. The flow chart of the algorithm and the explanation is provided in the poster below. Publications: 1) Modeling the Simple and Complex Cells in Visual ...

  • Design & Development of adaptive search engine with near-real time performance for use in assistive applications Guide: Prof. Dr. Rahul Banerjee, SDETU Chief, BITS Pilani, Pilani Campus. This project, aims at helping the elderly in old age homes, who have very less family support & for them to be able to connect to the world by simple voice driven commands. To make this adaptive for every human, we devised a mechanism to divide every sentence into an action-reaction analogy. So, every sentence the user says (input), is recorded and, over time an optimal match for that sentence is returned (output). Here in the program we call every input sentence as an "Action" sentence. This Action sentence triggers the search engine, which looks for the output (which we refer to as "Reaction" sentence). The most important challenge ...

  • Feasibility Study of Using Driving Simulator to Investigate the Effect of Temporary Rumble Strips Guide: Prof. Dr. Nigamanth Sridhar, Prof. Dr. Wenbing Zhao. Cleveland State University, OHIO, USA. In this project, we report a study on the feasibility of using a driving simulator to investigate the effect of temporary rumble strips on the car/humans. This study is part of the project which investigates how to effectively use rumble strips to reduce vehicle speed and increase driver alertness when they enter a short-term work zone. To reduce costs and avoid safety hazards, it is highly beneficial to use a driving simulator to study rumble strip design and placements instead of completely relying on field tests. However, it is crucial to establish the validity and to understand the restrictions of using the driving simulator ...

  • Driver Drowsiness Detection System (D3S) Self Initiated Project. Designed a real time drowsiness detection system where input parameters (Physiological: Eye blink rate, Eye blink time, Eye gaze. & Performance: Steering wheel angle, Accelerator & Brake pedal handling) are fed into a new Adaptive Neural Fuzzy Inference System algorithm which takes decisions about the drowsiness level of the driver with respect to the parameter's deviation from normal behavior. After the drowsiness level is predicted, a very specific alarm is generated which increases the alertness of the driver. This alarm is also called the brainwave which brings his/her drowsiness level out of dangerous levels. A video below shows the performance of the eye blink setup. A flow chart of the algorithm is shown below - This project was ...

  • Thought-Processor – A non-invasive method for the paralyzed to communicate Self Initiated Project. An image processing and emotional analysis based real-time communication medium for patients suffering from locked-in syndrome or complete/partial paralysis. This project assists such individuals in communicating their needs in a simple and accurate manner. The image processing algorithm used, is aimed at obtaining the patient’s line of sight and a skin conductance circuit constantly measures his emotional activity levels. The project enables the patient to select from a list of basic needs, displayed on the screen. He/she can also type words to communicate with expressions with an accuracy of 30-40 alphabets per minute. This experiment was tested on a fairly large sample set (on healthy humans) and has proved a promising ...

  • Virtual Air Guitar Self Initiated Project. This project was awarded the Silver Medal in Apogee'10 - The Annual International Technical Festival of BITS Pilani, India. Virtual Air Guitar is a System on a Chip, which replaces the guitar by "hand gloves" and an electronic circuit where signals are send to electro-acoustic transducers to produce sounds. Here movements of fingers in the air produce the same sound as a guitar. The design of the Virtual Air Guitar (VAG) is shown below, as a schematic diagram.    Right Hand (Top & Bottom)                               Left hand (Top & Bottom)The boxes denote the position of the circuit boards. The mechanical system which determines the fret positioning is shown below in the diagram - Mechanical System Joining both the handsB ...

  • Preoccupo Consulo Lubricus (PCL) Guide: Himanshu Dutt Sharma, Scientist, Government of India, Central Electronics Engineering Research Institute, Pilani.  I developed an intelligent system to predict the possibility of slipping in a dynamically changing environment. An accelerometer sensor was used to predict the possibility of skidding using physical-mechanics equations in the back end. This predicted decision was given to the driver alerting him before skidding and thus giving him more time to react to such a situation. Four kind of situations were developed:Skidding on Flat RoadsSkidding on Banked RoadsToppling on Flat Roads, &Toppling on Banked RoadsThe final equations used are presented below: Equations to Prevent Skidding Equations to Prevent TopplingNow, after these equations were developed mathematical modeling was done ...

  • Device Controlling System Self Initiated Project. Designed a System on a Chip, which could be used to control devices in an industry or home, which are inaccessible for humans. This could also be used for old people for controlling all home appliances from only one single device and sitting in any place. Data communication was done using RF modules. The USP of the device is its low cost of only $8/-.  This device runs perfectly within a range of 50m and was awarded the bronze medal, for the ease of use and low cost, in the Communication & Networks category at APOGEE’10 – The Annual International Technical Festival of BITS, Pilani.

  • Design of a Ripple Type algorithm to find Transitive Closure in graphs Guide: Prof. Dr. Nigamanth Sridhar, Cleveland State University, OHIO, USA. Designed an algorithm to find the transitive closure in graphs. The algorithm has a unique property where time complexity is inversely proportional to the average branching factor of a graph. In fact it challenges the optimality of Warshall's O(n3) algorithm which is used in most books on algorithms. The time complexity of my algorithm is O(N3/E3). Where N is the number of nodes and E is the number of edges. The developed algorithm was initially hypothesized using flow charts and then it was tested by formally proving the hypothesis using running code. The input test case was varied from 10 to 500 nodes ...
