Week 11

Video Tracking

This week we'll move from hand-coded brightness/color tracking on to motion tracking using Blob Detection. A "blob" here is any area of change in the image - either between one frame and the next, or as a comparison between a frame and an initial reference frame. Blob detection can track multiple things and also tell you how big they are, without assuming anything like specific colors or bright lights. TTCPro is very good at this; JMyron is too, and will also give you an outline of points around the blob to use for drawing shapes or other purposes.
