Variable Window Stereo Matching Method Based on Correspondence Peak Image

After analyzing unsuccessful causes on area-based stereo matching methods,we find that there is a close relation between image area speciality and its correspondence peak image shape.An adaptive arithmetic to choose correspondence windows sizes is proposed through watching correspondence peak image shapes according to input window sizes.In addition,a support-weight way based of gray difference and distance is adapted,which overcomes the flaw of disparity discontinuities in matching windows in a certain extent.A good result has been obtained.
