Blob Detection with Core Image

Hello,I am trying to write a program that will detect bright "blobs" of light in an image and then track those blobs of light. I would be a Cocoa version of OpenTouch at http://code.google.com/p/opentouch/. I am wondering the best way to do this sort of image processing with Cocoa frameworks. I ha
