Abstract
A method for determining if a first pixel and a second pixel belong to a same surface includes: determining a spatial-difference value for the first pixel and the second pixel; determining one or more vision-difference values for the first pixel and the second pixel; determining, from the spatial-difference value, an initial same-surface probability value for if the first pixel and the second pixel belong to the same surface; determining, from the one or more vision-difference values, a first vision-difference probability value for if the first pixel and the second pixel belong to the same surface; determining, from the spatial-difference value and the one or more vision-difference values, a second vision-difference probability value; determining, from the initial same-surface probability value, the first vision-difference probability value and the second vision-difference probability value, an improved same-surface probability value for if the first pixel and the second pixel belong to the same surface.
