This paper presents the auto-matching algorithm and applies it to human face warping. In this algorithm, we first prewarp the two origin images to make their epipolar lines parallel to the horizontal scan-lines. Then we detect edge points on the scan-lines of the first image by the use of the Gauss first differential filter and match the corresponding points on the same scan-lines of the other image. With these corresponding edge points, we can segment the scan-lines of the two images. In the end, we use affme transformation to obtain more exact corresponding relation of these points. Some experiments have proved that the algorithm is simple and doable.
