Abstract:
1. A method for determining a similarity or dissimilarity measure for a selected pixel of a first image relative to another selected pixel in a second image, the first image and the second image forming a stereoscopic image pair or part of a multi-view image group, the method comprising the steps of: determining a first support window containing the selected pixel in the first image; determining a second support window containing the selected pixel in the second image; calculating one or more statistical properties of the selected pixel in the first image to define a probability distribution for the selected pixel in the first image; aggregating pixel similarity or dissimilarity between the first support window and the second support window using only those pixels belonging to the probability distribution for the selected pixel in the first image with a probability above a defined threshold, which is derived from the one or more statistical properties of the selected pixel in the first image.
