Feature detection, boxes, and optical flow look awesome.
Reviewers suggested playing around with footage that's more playful, fun, and intimate (as opposed to the more conventional surveillance footage).
Features:
• Needs optical flow working on local regions of the image
• Leaving optical flow trails / motion vectors
• Heat map using frame differencing
• Face detection
Jonathan is experimenting with FaceShift for a separate but related visual system that's more about animation, motion capture and interactivity.
