I need advice on the suitable filtering techniques and also a good colour and shape detection algorithm.

I'm trying to use colour detection together with shape detection to create a computer mouse. Basically the idea is:

camera detects a particular shape and colour and acts as a right/left CLICK.
camera detects 2 similar shape and colour and acts as a MOVE cursor function.

I would need help for the training features too, as in the detection of the colour and shape at different distances from the camera.

Examples of reliable codes are helpful and appreciated. =)
