Window based matching is used for determining a depth map from images obtained from different orientations. A set of fixed matching windows is used for points of the image for which the depth is to be determined. The set of matching windows covers a footprint of pixels around the point of the image, and the average number (O) of matching windows that a pixel of the footprint (FP) belongs to is less than one plus the number of pixels in the footprint divided by 15 (O<FP/15+1), preferably less than one plus the number of pixels in the footprint divided by 25 (O<FP/25+1). |
