Title: Stereo image matching apparatus and method

Abstract: The present invention relates to a stereo image matching apparatus and method. The stereo matching apparatus includes a window image extraction unit for extracting window images, each having a predetermined size around a selected pixel, for individual pixels of images that constitute stereo images. A local support-area determination unit extracts a similarity mask having similarities equal to or greater than a threshold and a local support-area mask having neighbor connections to a center pixel of the similarity mask, from each of similarity images generated depending on differences in similarity between pixels of the window images. A similarity extraction unit calculates a local support-area similarity from a sum of similarities of a local support-area. A disparity selection unit selects a pair of window images for which the local support-area similarity is maximized, from among the window images, and then determines a disparity for the stereo images.
