Implemented kernels and base architecture for hardware-accelerating path-finding algorithms likeAstar RRT and PRM. Benchmarked existing implementations alongside OpenCL and OpenVXkernels. Improved performance of algorithms by over 100x on provided hardware.

Implemented graphics animation and editing interface for an airline scheduling software with highquality graphical data visualization requirements. Built it on a DirectX based graphics engine (above)and provided interfaces for fast updates and improved frame rates. Implemented complex businesslogic for flight editing operations with many cases and scenarios. Troubleshooted issues withrendering on third-party controls (Telerik).

Implemented a full-fledged face detection recognition and analytics software including a pre-salesdemonstrator for recording statistics of users moving in front of Digital signage cameras usingOpenCV based Face detection and recognition. The demonstrator also included a speech synthesizerin order to talk to the users at real-time and convey statistics like their engagement times glancecounts and predicted age and gender. It also involved background crawling of frames historicalinformation to improve the predictions. Some modules like Age and gender recognition wereintegrated via Matlab-.NET Interop and inter-process communication (using sockets).

Generic 3D graphics engine and viewer with editing features for integration into 2D/3D applicationsand for rendering 3d interactive content on Microsoft Surface platform (Samsung SUR40 touchtables) and eBoards (65 touch boards used in classrooms). It includes implementation of visualize-cum-editor application which can read many proprietary formats and display overlaid semi-transparentinteractive 2D/3D content and/or images/videos. A new proprietary visual document format wasdesigned for handling various content and abstract interfaces were provided for integrating contentfrom other content providers.

This project is a feasibility analysis cum product development for a closed loop system for diabetescontrol. The system involves a continuous glucose monitoring (CGM) device attached to patientsbody which is communicating to an android based Remote control (RC) via Bluetooth low energy. TheRC analyses required amount of insulin required by the body and sends commands to insulin pump(via BT/BLE) for injecting insulin. Pumps from multiple manufacturers are being supported. Dedicatedcommunication processor is provided in the RC for real-time communication between the devicesinvolved. UART interface was used for communication between these processors.

This project was a CATIA-CAA customization suit for aerospace client. The implementation involvedautomation of several design checkpoints to verify and validate a designers CAD output. This tooliterates through every geometry inside a CATIA CAD file (CATProduct) and checks for clashescontacts and clearances. It verifies the accuracy of specified geometry parameters and automaticallygenerates a pre-formatted Excel report.

The software was intended for TV set top boxes that show context sensitive info-pages. Userinteraction was performed through the TVs remote control. The software includes a viewer as well asan editor for creating new info-pages (by the broadcasting companies). Written completely in C# ituses a classic MVC design pattern to handle the viewing and editing of the model.

This project is a video creator used to make custom videos for a research on crowdsourcing. Thevideos were created at run-time out of instructions from a CSV file which described events to happenduring the video at specific intervals. The frames were rendered using OpenGL and GLUT was usedfor windowing and user inputs.

3D Viewer built for visualizing and configuring input and outputs of a Feature Group Optimizer. Theoptimizer groups all the features in an automobile part to analyse the most cost-effective way tomanufacture the part. This grouping needs to be visualized to give the development team an idea asto how their results look like. The visualization allows show/hide an operation or group(s) ofoperations check for overlap between operations their directions and sizes. This GUI was builtprimarily to configure the results of the optimization algorithm also used as a generic viewer toview/rotate/pan/zoom 3D IGES geometries.
