Scene is a computer vision framework that performs background subtraction and object tracking, using two traditional algorithms and three more recent algorithms based on neural networks and fuzzy classification rules. For each detected object, Scene sends TUIO messages to one or several client applications. The present release features GPU accelerated versions of all the background subtraction methods and morphological post processing of the object blobs with dilation and erosion filters, implemented in OpenCL. ...

...Log timestamp, x and y to comma-separated value (.csv) file importable to spreadsheet. Uses Lukas-Kanade algorithm and based on lkdemo.cpp in OpenCV, stripped down to track single point in high contrast against a uniform background. Based on the BSD licensed OpenCV, TrackXY also has BSD-style license. I am a bit embarrassed to be posting this here, because it's such a rudimentary program, but I couldn't find any other ready-made program that would track an object in real-time from webcam, other than an $80 special-purpose program used in the original (torsion balance) experiment we were replicating. ...

...It applies probabilistic spatiotemporal macroblock filtering (PSMF) and partial decoding processes to effectively detect and track multiple objects with fast computation in H.264|AVC bitstreams with stationary background. The codes were written in Visual C++. For more details, please visit https://www.wonsangyou.com/research/aivision. If you need technical help, please send an email to wyou(at)kaist.ac.kr.
