  • Stereo matching is the key of reconstruct-
    ing 3D face model from 2D face images and Barnard's al-
    gorithm is one of the classical stereo matching algorithms
    based on feature points. In order to enhance the stability
    of extracting feature points, reduce computational com-
    plexity and minimize the e®ect of subjective factors, in this
    paper, Barnard's algorithm of edge point matching was im-
    proved from two aspects: edge point sets of left and right
    face images were extracted with dyadic wavelet transform,
    rather than comparing gray values of adjacent pixels; on
    the other hand, edge points in binocular stereo face images
    were matched under epipolar constraint in parallel binoc-
    ular stereo matching. Experimental results demonstrate
    that stability and e±ciency of stereo matching algorithm
    are both improved.
