Tracking and Surveillance Projects | Shawn Lankton Online
I took a special topics course in Spring 2008 at Georgia Tech, ECE 8893: Embedded Video Surveillance Systems. The course included three projects, each shown below. Detailed information about the algorithm is in the source code comments. (All the source is in Python)

Project 1: Activity Density Estimation

Use background subtraction to find moving foreground objects in a video sequence. Then, color-code regions with the most activity. Here is the result:


Project 2: Styrofoam Airplane Tracking

Find all white styrofoam planes in the scene and track them throughout the scene. We used color thresholding and simple dynamics to do the tracking.


Project 3: Pedestrian Tracking

Count and track the pedestrians that cross on a busy sidewalk. We use a combination of motion estimation via background subtraction and feature matching using the Bhattacharyya measure.

Final Report: p3.pdf

Most of this code is very hack-y because it was done quickly. However, it was
fun to learn Python, and the class was enjoyable overall.

Matter & Interactions | Contemporary calculus-based physics
"Matter & Interactions is a textbook by Ruth Chabay and Bruce Sherwood (John Wiley & Sons, 4th edition, 2015) that emphasizes a modern perspective on the calculus-based introductory physics curriculum taken by science and engineering students. it engages students in: Starting analyses from fundamental principles rather than secondary formulas Making macro-micro connections, based on the atomic nature of matter Modeling physical systems: making idealizations, simplifying assumptions, estimates Constructing computational models to predict the time evolution of system behavior"

GlowScript IDE
"GlowScript is an easy-to-use, powerful environment for creating 3D animations and publishing them on the web. Here at, you can write and run GlowScript programs right in your browser, store them in the cloud for free, and easily share them with others. Thanks to the RapydScript compiler, you can use VPython here."

"VPython makes it easy to create navigable 3D displays and animations, even for those with limited programming experience. Because it is based on Python, it also has much to offer for experienced programmers and researchers."
