基于新的加权Hausdorff距离的图像匹配
Image matching based on new weighted Hausdorff distance
【摘要】 Hausdorff距离(HD)用于度量两个点集之间的距离,它不要求点之间的一一对应,是一种模糊度量,因而在匹配来自不同传感器的图像时广泛使用。在分析了传统HD算法的基础上,提出了一种基于结构张量加权的HD,称为STWHD。红外与可见光图像匹配的仿真实验表明,其抗噪能力较传统的HD算法有较大的提高。
【Abstract】 The Hausdorff distance(HD) that measures the distance between two sets of edge points extracted from template image and test image,is commonly used in image matching.The conventional HD is analyzed and a new HD weighted is proposed based on structure tensor,which is called Structure Tensor Weighted HD(STWHD).By matching visible image and infrared image with different noises,the performance of conventional and proposed HD is compared.Result shows that the anti-noise ability of STWHD is improved.
