Image matching based on contour is an important issue in computer vision, navigation and pattern recognition. The image matching methods like curvature-based methods and corner-based methods have poor robustness to the contour's noise and distortion, and some matching methods are applied only to closed contours. A novel contour representation and matching algorithm, based on local curvature scale,...
This paper presents a stereo image coding method. We first use a new stereo matching method with difference-based adaptive searching windows to get the fine disparity. Then, we encode the disparity instead of one channel of the stereo image while the other channel is encoded normally. The stereo matching employs the continuity of difference of stereo images to compute the size of adaptive searching...
This paper proposes a matching template based on first order differential coefficient for fast edge extracting after analyzing and synthesizing the traditional algorithm of edge detection. The method is able to effectively thinning the image edge and increase the accuracy and efficiency.
