In stereovision, the use of frequency domain methods raises the problems of the choice of a family of filters and a strategy to use it. This paper compares three families : Gabor filters, finite prolate spheroidal sequences and Weng's Windowed Fourier of Gaussian (WFG). Then a comparison between two strategies is done : an image-based choice of filters and(More)
In this paper, we first review the main features of a general regression problem in computer vision. Then we underline how the underlying difficulties have been independently addressed by using a set of tools coming from optimization or statistics and how in particular applications, some specific needs have already found relevant answers. Unfortunately, no(More)
