Abstract:

There are several methods for forming a scale-space and they may be classified as being based on diffusion or morphology. However it is rare for the methods to be compared. Here we outline a method for such a comparison based on robustness and give results for linear diffusion, the most widely studied method, and a sieve (a new morphological method). We find that the standard diffusion-based systems are not as insensitive to noise and occlusion as one might wish.
