Abstract:
1. A processing method for a pair of stereo images, the stereo images comprising a source image and a destination image, the source image comprising a plurality of source pixels and the destination image comprising a plurality of destination pixels, the processing method comprising: determining a plurality of source key pixels having a key characteristic in the source image; determining a plurality of destination key pixels having the key characteristic in the destination image; providing a plurality of overlap records and a plurality of disparity records associated with the source key pixels; sequentially identifying a plurality of overlap levels between the source image and the destination image for a plurality of image lateral shifts, each image lateral shift having a corresponding overlap level; updating the disparity record and the overlap record of a selected key pixel to a most-likely disparity and a maximum overlap level; extracting an edge image comprising a plurality of edge pixels from the source image as the source key pixels; and increasing source pixels within a predetermined range neighboring the edge pixels to serve as the source key pixels, wherein, the selected key pixel is selected from the source key pixels, the maximum overlap level is a maximum among a plurality of associated overlap levels associated with the selected key pixel, and the most-likely disparity corresponds to the maximum overlap level.
