2D is nice, but these days I’m getting interested in doing computer vision in 3D. One way to get 3D data is to use two cameras and determine distance by looking at the differences in the two pictures (just like eyes!). In this project I show some initial results and codes for computing disparity from stereo images. Read the rest of this entry »

In this project I look at engineering from a different perspective… the business perspective. My team and I started with an idea: Track cars in a parking lot and use the information to help the whole operation run smoother. From there, we researched, though, and schemed until we had a sturdy business plan for the new venture. Read the rest of this entry »

My newest research focus has moved away from medical images and towards moving images… And instead of finding organs and tumors, I’m tracking moving objects in the videos. Check out some of my latest successes (and failures). Read the rest of this entry »

This algorithm analyzes statistics in small local regions of an image to try and separate the foreground from the background. This is an active contour segmentation technique, meaning a curve (or surface) is deformed over time to iteratively improve the segmentation until an optimum is reached.

I had a lot of fun “teaching” a Sony Aibo to find and pick up “trash.” This project uses some rudimentary computer vision, simple tracking, audio location, and neural network classification. Plus, its cute! Read the rest of this entry »

This was a quick and dirty project for a robotics class that I took at Georgia Tech in 2005. In this project, I built a Matlab simulator for testing out some simple obstacle avoidance/navigation code. My hope is that someone uses this a springboard to make a more complete version.

What started as a class project has developed into a prototype algorithm for a medical instrument. Read the rest of this entry »

Hacking into computers is all well and good if you’re a CS person, but I’m a EE. This device plugs in-line with the PS2 port and hijacks key presses. When a username is typed in, it records the following password. Read the rest of this entry »

Doing this project really turned me on to systems and controls theory. A friend and I implemented a fully functioning PID motor speed and positioning controller onto a PIC MCU. This is a pretty thorough guide to building this very hand robotics peripheral. Read the rest of this entry »

This was a simple Matlab project, but it can be very handy for generating touch tones for telephony hacks. In fact, try it out, you can dial your phone just by holding it up to the speaker! Read the rest of this entry »
