I got the privilege of developing some of the Super Computing 2012 (SC12) booth demos for AccelerEyes, to showcase ArrayFire. Above is an ArrayFire demo running at SC12 on an nVidia GPU. This demo (source code HERE) uses OpenCV to capture webcam video and processes the stream in several different ways, in real-time. From top-left to bottom-right: Sobel filter, ArrayFire logo, Motion (frame differencing), Source image, Histogram … Read more
This page constitutes my required external learning portfolio for CS 7495, Computer Vision, taken in Fall 2011. In it, I discuss what I have learned throughout the course, my activities and findings, how I think I did, and what impact it had on me. About me I am a coffee fanatic that is into computers, photography, computer … Read more
Update 1: LibJacket has been renamed to ArrayFire. Update 2: Huang Chao-Hui was nice enough to port the LibJacket code mentioned here to ArrayFire – see his work here. As one of my Computer Vision class projects, I decided to implement optical flow, because I wanted to learn more about optical flow, and also I wanted to code it … Read more
Update: one year later: ArrayFire+OpenCV The OpenCV library is the de-facto standard for doing computer vision and image processing research projects. OpenCV includes several hundreds of computer vision algorithms, aimed for use in real-time vision applications. LibJacket is a matrix library built on CUDA. LibJacket offers hundreds of general matrix and image processing functions, all running … Read more
Connected Component Labeling (CCL): “is used in computer vision to detect connected regions in binary digital images”, and sometimes referred to as blob coloring. Motivation: To keep AccelerEyes’ ever expanding GPU library growing, over a few weeks of this summer I took on the project of writing a CUDA version of connected component labeling to be used in … 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
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
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
