1. A computer-implemented method for correlating stereoscopic images comprising: determining a region around an individual pixel of a first stereoscopic image, wherein the first stereoscopic image has a corresponding second stereoscopic image; determining an amount of detail for the region, wherein the amount of detail comprises at least one of a sum of the absolute values of gradients in the region around the individual pixel, an entropy measurement in the region around the individual pixel, or a variance in the region around the individual pixel; comparing the amount of detail to one or more predetermined thresholds to determine a support window size of a support window for correlating the individual pixel to a corresponding pixel of the second stereoscopic image; and determining a support window shape of the support window based at least in part on the amount of detail, wherein the support window shape comprises a rectangular shape having a shorter edge in a greater gradient direction of the region.
