一种平移旋转图像的角点匹配方法
Corner matching for translation and rotation image
摘要
Abstract
During the course of image corner matching, the translation and rotation of object image often affect the matching results. A corner matching method is proposed based on deterministic annealing. Harris corner detection is used to extract the corner points respectively from object and matching image, and the gradient information of the corner points from the autocorrelation matrix are also calculated. The free energy function of deterministic annealing is constructed by combining the gradient information and the affine transform. The optimization affine transform parameters are obtained by optimizing the free energy function. Corner matching between object and matching image are complemented through the affine trans-form. Simulations show that this method can effectively achieve the corner matching when the object image occurring translation and rotation.关键词
