Basic PHP Voting Script

MapleMario showed a good understanding of my requirements and even suggested ways to improve them with the code / design of the script. He showed excellent skill in getting a working framework of the script up within 24 hours, provided extra help when needed, and overall far exceeded my expectations. Will endeavor to work with again.

Automated Offside Detection in Soccer

TJHSST

Discussed the problem of human offside detection in soccer and outlined several proposed solutions. Explained how I used the Python OpenCV library to detect players’ movement on a soccer field via frame-by-frame analysis of videos using optic flow detection and later Haar Cascades. Implemented a stable, high-accuracy 2D offside detection algorithm based on inputted key player points.
