Abstract
Displacement of a first block of pixels from a first to a second image of a scene is determined for applications of automated distance computation. The selection of corresponding blocks in the two images is performed and verified as follows. A first block is taken from the first image. A first region is selected from a set of first regions in the second image, so that a difference between an image content of the first region and of the first block is minimal among the set of first regions. A second block is taken from the second image, the second block containing at least part of the selected first region. A second region is selected from a set of second regions in the first image, so that a difference between an image content of the second region and of the second block is minimal among the set of second regions. A first displacement between the first block and the selected first region is compared with a second displacement between the second block and the selecting second region. If difference between the first and second displacement is significant, the correspondence between the blocks is treated as unreliable.
