However  the wavelet representation suffers from the dependency of the starting point of the sampled contour. For overcoming the problem that the wavelet representation depends on the starting point of the sampled contour  the Zernike moments are introduced  and a novel Starting-Point-lndependent wavelet coefficient shape matching algorithm is presented. The proposed matching algorithm firstly gains the object contours  and give the translation and scale invariant object shape representation. The object shape representation is converted to the dyadic wavelet representation by the wavelet transform. And then calculate the Zernike moments of wavelet representation in different scales. With respect to property of rotation invariant of Zernike moments  consider the Zernike moments as the feature vector to calculate the dissimilarity between the object and template image  which overcoming the problem of dependency of starting point. The experimental results have proved the proposed algorithm to be efficient  precise  and robust.   Feature-based Registra- tion Algorithm Using Invariant Line Moments 期刊论文  OAI收割 光子学报, 2003, 卷号: 32, 期号: 9, 页码: 1114-1073 Yang Jing; Qiu Jiang; Wang Yanfei; Liu Bo 收藏  |  浏览/下载：1004/37  |  提交时间：2010/01/12 Line invariant moments  Feature extraction  Image registration  Satellite imagery
