• Appointment in department of Electrical Engineering (through FITT, IIT Delhi) in research project funded by Cadence Design Systems. Worked under CTO office in the IP group (based primarily in San Jose, CA) that pursues the objective of driving technical innovation in deep learning for Tensilica Vision DSPs for imaging and computer vision. Main contributions included (but not limited to) code enhancements, prototyping of ideas from recent deep learning research literature and providing support functions for following:-
• > Performed training, validation and testing of convolutional neural networks for (a) object detection in images and (b) semantic segmentation of road scenes (an essential component of advanced driver assist systems).
• > Explored novel approaches for improving correct detection rate of CNN through training on ground truth images in non-spatial domains. Performed analysis of these approaches by computing statistical parameters including image energy distribution, image reconstruction accuracies and run-time computational complexity over standard road image data sets including KITTI and Cityscapes.
• > Generation of ground truth image data for CNN training and validation through a combination of scripting, collection from industry standard data sets including ImageNet, Microsoft Coco, KITTI, Cityscapes and through manual annotation.
• Development environment: MATLAB, MatConvNet, Cadence's proprietary deep learning framework, Python.

• Main contributions and responsibilities include following:-
• Developed a 3D graphics visualization engine enabling mouse-controlled viewing of Finite Element Model (FEM) of human body. Key features implemented: 3D rotate, zoom and pan of model mesh with a coloring scheme based on anatomical parts and a wireframe overlay. Mouse-picking of mesh nodes based on ray-casting method.
• Optimized feature performance by enhancing OpenGL command sequence for better ordering of model data in vertex buffers and minimizing computationally expensive OpenGL function calls for rendering.
• Implemented repositioning module for performing mesh deformation for standard movements of anatomical parts in vehicular driving scenarios. Algorithm used was based on Delaunay tetrahedralization of 3D geometry enclosing the mesh.
• Optimized repositioning algorithm by implementing strategy for minimizing search space of tetrahedrons for mapping mesh nodes. Efficiency was improved significantly and run-time reduced from several hours to seconds for entire mesh containing millions of nodes and elements.
• Developed a graphical toolbox module for GUI-based management of geometrical primitives including 3D points, point sets, axes, coordinate reference frames and 3D planes.
• Implemented parser for reading/writing model data from/to Visualization Toolkit's (VTK) XML-based file format using the open-source TinyXML-2 library.
• Ported part of code base from legacy implementation (MS Visual C++ with MFC) to a next-generation version using Qt framework for enabling platform-independence in the application.
• Provided software engineering knowledge transfer to team members from Mechanical Engineering domain, and technical mentorship to junior project members and interns.
• Development platforms / technologies used: MS Visual C++ with MFC (under MS Visual Studio 2012), C++ Boost libraries, OpenGL, Qt, XML, CMake, Subversion, Git.
