Abstract
A solution for determining a similarity or dissimilarity measure for a selected pixel of a first image relative to another selected pixel in a second image is described. The first image and the second image form a stereoscopic image pair or part of a multi-view image group. In a first step a first support window containing the selected pixel in the first image is determining. Then a second support window containing the selected pixel in the second image is determining. Subsequently one or more statistical properties of the selected pixel in the first image are calculated to define a probability distribution for the selected pixel in the first image. Finally, pixel similarity or dissimilarity between the first support window and the second support window is aggregated using only those pixels belonging to the probability distribution for the selected pixel in the first image with a probability above a defined minimum.
