基于MIC角点检测的改进算法

针对MIC角点检测算法具有角点定位不够精确、误检、漏检等缺点，提出一种改进的MIC角点检测算法．为了克服MIC角点检测算法角点定位不准确的缺点，该检测算法利用最小二乘技术对角点局部方向线进行拟合，实现角点的亚像素定位；同时为了克服MIC角点检测易混淆边界点和角点的缺陷，引入检测直线，根据拟合点到检测直线的距离是否大于某一阈值剔除边界伪角点．实验结果表明，改进的MIC角点检测算法角点检测性能明显提高．

An improved algorithm based on MIC corner detection

For the MIC algorithm's disadvantages of being unable to determine precisely the position of corners and tending to detect the false corners and miss the corners,a novel algorithm of corner detection is presented in this paper.According to the novel algorithm,corners are re-located to sub-pixel accuracy by fitting their local orientation lines by the least squares technique.In order to overcome the disadvantage of tending to confuse edge points with corners,introduce detection line and calculate the distanc...
