April 2011 Abstract As a final project for my Computational Photography class at Georgia Tech, I created an application that uses a single video camera to create tonemapped HDR images in real time. This project’s inspiration comes from Soviet Montage Production’s DSLR HDR video. The app runs on Linux PCs (using USB or Firewire … Read more
March 2011 With the help of Motodev Studio for Android, I’ve extracted the android-opencv JNI camera example and spawned a fork of my original computer vision app, Viewer, to an OpenCV version: ViewerCV. Both are available on Git Hub as open source software example of doing Computer Vision on Android with OpenCV. Viewer Features: *FAST Features (default android-opencv example) *Square detection *Sobel … Read more
Note: I am by far no expert on this – (I only spent the past few days trying to wrap my head around automake, and before that, never opened a configure.ac file before) – just wanted to share my experiences. Below is an excerpt from configure.ac and Makefile.am files I modified to add CUDA to an … Read more
I got an incredible opportunity to travel to Las Vegas and give a short talk at the 2011 AT&T Developer Summit on a few of the cool Android projects I’ve done in school. I was given only ~5 minutes to present 3 of my projects: RoadBump, FeedSpeak, and SPRIME – giving a student’s perspective on Android programming. … Read more
January 2010 Over the holiday break, I finally created an Android app that allows image processing on the camera’s raw data, and displays it back on the screen. It only uses Java on the CPU for now, but in my free time I’ll be porting the code to OpenGL ES to run on the GPU, and … Read more
December 2010 My first project as a GRA under Rich Vuduc involved accelerating 3D Fast Fourier Transforms (3D FFT) with GPUs. The project was basically porting the open-source P3DFFT code (written in FORTRAN) to run on GPU(instead of CPU) clusters using CUFFT. Update: 04/16/2011 – This project has morphed into a SC11 paper – a draft … Read more
September 2010 I got an incredible opportunity (at the last minute!) to give a short talk at Nvidia’s GTC 2010 on what I learned about GPU matrix multiplication, while at AccelerEyes over the summer! Watch presentation here (I’m 19 minutes in)!
July 2010 OK, it’s not really a project, but I did learn a lot about GPU matrix multiplication over the summer, working at AccelerEyes. I re-worked the back-end CUDA code for the MTIMES Jacket function. I also modified it to accelerate SUM, MIN, and MAX. Checkout my MTIMES wiki page!
May 2010 FeedSpeak reads your Google Reader RSS news feeds aloud to you using Text-To-Speech. FeedSpeak started as a class project, but I now continue development on my own free time. Read the XDA-Developers blog post about FeedSpeak! (Note: reviewed for v1.9.6) FeedSpeak Pro for Android on AppBrain FeedSpeak Lite for Android on AppBrain … Read more
April 2010 Simple Powerline Remote Interactive Monitor and Enforcer SPRIME is an outlet that allows you to monitor power consumption and control power usage remotely, using a computer or even an Android phone. SPRIME is an open-source smart-grid technology. SPRIME GT-RNOC poster: SPRIME pictures: Awards SPRIME has made it on Hack-a-day! SPRIME has won … Read more
