| 摘 要： | 为改进角点检测算子的检测性能，提出了一种多尺度的Harris角点检测方法。该方法通过提取不同尺度下的角点，同时根据高斯核尺寸确定非极大值抑制窗口大小，然后根据角点响应函数值对每一尺度下检测出来的角点进行排序，且与前一小尺度下的角点进行比较，剔除伪角点，确保角点的精确定位。通过实验与几种角点检测方法检测结果相比，该方法检测角点的总误差小、错误率低，且匹配程度比原Harris算子显著提高，说明该方法是一种正确而有效的角点检测方法。

| Abstract: | To improve the performance of corner detector,a Multi-scale Harris Corner Detection(MHCD) method is presented.This method detects corners at different scales,and the size of the non-maximum suppression window is set according to the size of the Gaussian kernel.Consequently,the corners are ordered according to the value of corner response function,and the corners at current scale are compared with the corners at previous less scale so that false corners are removed to guarantee the best location for each cor... |
