You can start to look into OpenCV. There you have ready methods for this.

Here are some other links I found:

I would advise to use AForge.NET which is natively written in C#:
http://en.wikipedia.org/wiki/AForge.NET[^],
http://www.aforgenet.com[^].

This is the introductory AForge.NET page on contouring (edge detection): http://www.aforgenet.com/framework/features/edge_detectors_filters.html[^].

See also: http://www.aforgenet.com/articles/shape_checker[^].

By the way, if you prefer using OpenCV, you will need a .NET wrapper for it. Such wrapper does exist, called Emgu CV:

It mainly depends on what you are going to do with them. Are you going to recognize 3D shape from image? It's not going to be easy...
