Don't think whiskers will work on an "image".The input will be an image containing many kind shapes...
A literature search is a good place to start. Years ago I had to do a project requiring edge detection in images. The book I relied on was "Vision" by David Marr. This book was published in 1982 and no doubt there has been much progress in this area. Still, Marr's work was pioneering and may be sufficient for a simple project like this. Note, I don't mean simple in the sense that it will be easy, but this project involves some of the most basic problems in image recognition. In other words, solutions exist for this problem and you don't need to invent your own, but just learn the existing methods.What is the best way to begin this project?[/FONT]
