运用SI-Harris算子提取遥感图像点特征
Point Feature Extraction of Remote Sensing Image Using SI-Harris
摘要
Abstract
Scale Invariant Harris SI-Harris was applied to detecting interest points on remotely-sensed images and its rigorous formulas were derived. Then the focus of the paper was put on the experimental comparisons between the results obtained by Harris and SI-Harris on different resolution remote sensing images. The repeatability rate was used to quantitatively evaluate the experiment results. The experiments indicate that the repeatability rate of SI-Harris was obvious higher than Harris s. SI-Harris can be used to detect interest points on different resolution remote sensing images and then can serve the matching of different resolution images.关键词
