In this paper, we propose a new method to perform the first derivative estimation of a discrete intensity distribution. This approach is based on a non-additive aggregation proce...

In this paper, a concept called multiscale structure tensor is introduced, as an extension of the single-scale structure tensor. It is based on a redundant dyadic wavelet transfor...
