Software for Ground-truthing Articulated Tracking via Virtual Markers

This is a small Matlab GUI utility to ease the tedious task of defining the ground-truth 2D (x,y) location of body joints for articulated human body tracking in videos that have no associated motion capture data. The system partially automates the task of defining the 'virtual markers' by predicting a joint's (x,y) position in the next frame via template matching, and a human can correct the prediction interactively if necessary. For each joint, it takes 5-10 minutes to ground-truth 500 frames of video. Under Windows, any installed AVI codec is supported; under Unix Matlab only supports raw video.
