librealsense with ARM support (Apache v2):

A fork of the original librealsense library with the addition of ARM support. librealsense uses SSSE3 SIMD instructions for unpacking frames to the desired color format. This was necessary probably due to the nature of the pixel unpacking operations as they are inherently slow and are data parallel. Since SSSE3 is specific to x86 architecture, workarounds are needed for getting the code to compile under ARM. These workarounds are implemented in this fork. This library follows the original Apache v2.0 license of librealsense and is available on GitHub.

CodeFull Toolkit (Apache v2):

CodeFull Toolkit is an OpenGL-based visualization toolkit for .NET. The goal of this toolkit is to provide 3D visualization tools equivalent to the WPF 3D framework. CodeFull Toolkit is written in C# and uses OpenTK for OpenGL interop. This toolkit is released under Apache v2.0 license and is available on GitHub.
Some screenshots are available below.

CarveSharp (GPL v3):

Carve is a fast, robust constructive solid geometry library. CarveSharp is a .NET wrapper for Carve’s mesh boolean operations. Using CarveSharp, set operations such as intersection, union, differencing etc. can be performed on triangular meshes. CarveSharp is written in C# and released under GPL v3 license in GitHub. CarveSharp uses the CodeFull Toolkit library.

Below is the result of subtracting a cube mesh from a chair mesh (the chair mesh was obtained using Kinect Fusion).

CudaHoG (Apache v2):

CudaHoG is an efficient implementation of Dalal & Triggs Histogram of Oriented Gradients in CUDA.
It is written in C++11 with optimization in mind. Features can be extracted using the library or the MATLAB MEX interface that it provides. The project is open source (Apache v2.0 license) and available on GitHub.

Here are some screenshots of the results of feature extraction (click each image to enlarge).

TransScale (Apache v2):

TransScale provides transparent scalability for using multiple GPUs with JCuda. The library facilitates agile CUDA development in Java using JCuda. With TransScale, it is now easy to load modules on single or multiple CUDA-enabled GPUs and harness their processing power.

TransScale also provides wrappers for 2D CUDA primitive arrays of structs with arbitrary number of fields (such as a 2D array of char’s representing an array of colors in ARGB space). These 2D allocations can be automatically pitched if possible and the pitch values are converted to a number that can be treated as a regular “width” similar to any 2D allocated array. The wrapped pointers are extensions of CUdeviceptr which allows transparent manipulation using JCuda. The project is open source (Apache v2.0 license) and available on GitHub.

CUDA Extensions for Genetic Programming in ECJ (Apache v2):

This library provides support for automatic parallel tree evaluation and fitness calculation on GPU for ECJ using JCuda and TransScale. The project is still under development. However, most problems should be able to benefit from the massive processing power of the graphics cards with minor modifications. The project is open source and available on GitHub.

M2X Messenger (GPL v3):

As a hobby project, I worked on an open source Yahoo! messenger client for the Android OS. Surprisingly, there are no other open source Yahoo! messenger clients for Android despite the fact that Yahoo! is very popular. The project is open source and available here. The graphics and UI design (excluding some of the icons) as well the application logos are all done solely by me.

Here are a few screenshots of the program in action (click each image to enlarge).
