April 2010 I find graphics card programming fascinating. I presented a UROC Poster on GPGPU Molecular Dynamics analysis and visualization on the GPU at the 2010 Georgia Tech Undergraduate Research Symposium. I also had a cool demo set up of the system running (above), along with my Android bonds visualization client.
March 2010 I recently started playing with the Nvidia CUDA SDK Samples involving image processing. I extracted the SobelFilter kernel and made it run off my USB webcam using OpenCV – the two live modes are single-channel-gray and three-channel-rgb. I wrote two different basic kernels on my own that did binary thresholding and found the most dominant RGB value. Now on Google Code! cam-cuda-sobel
August 2009 This is an Arduino microcontroller that I wired into my car’s ECU and programmed to calculate the instantaneous/average miles per gallon of my 2002 Honda Civic. The circuit reads pulses from the Vehicle Speed Sensor and Fuel Injector wires. It is wired into my car via a USB cable. It’s pretty accurate once calibrated. My … Read more
July 2009 I competed in the 2009 Intelligent Ground Vehicle Competition, on the Georgia Tech RoboJackets Team. Our robot: Candi. I developed the computer vision algorithms to navigate an autonomous vehicle using only a vision camera. Our team ranked 6th place nationwide. Competition photos here. I wrote all of the vision and mapping code! The robot navigated using a single camera only. … Read more
September 2008 A project at GTRI FPTD I worked on involving combining a color vision system with a 2D laser projector. Case Study about the project here: Using Lasers to Identify Substandard Food. With Python and OpenCV, I got the system to find contours with the camera, and tell the laser to draw them in real-time. The goal was to … Read more
June 2008 I used a PIC microcontroller in a circuit to measure my car’s MPH. It measures the frequency of pulses from the Vehicle Speed Sensor, and converts it to miles-per-hour. A summer project involving programming a PIC micro controller to measure my Honda Civic’s MPH. The circuit I made measures the frequency of the pulses coming from … Read more
Yesterday, I was stoked about FeedSpeak getting posted on the front page of the xda-developers site! This was totally unexpected and definitely made my day. A few days ago, a friend had recommended that I advertise the app in the xda-developers forum, so I created a simple post for FeedSpeak Pro. After posting though, I learned … Read more
