摘要:
Harris 角点检测需要计算图像中每一个像素点的角点响应函数值（CRF），这使得算法运行速度慢，不能满足 实时性的要求。针对这个缺点，文章提出了一种改进算法。改进算法通过分析图像中每个像素点 8 邻域范围内相似像素点分布 情况，剔除那些非角点的像素点，并选出潜在的角点像素点作为下一步 Harris 检测的候选点，从而大大提高了算法的运行效率
Abstract:
Harris corner detection algorithm needs to calculate corner response function of each pixel, which makes the algorithm low efficiency and poor real-time performance. An improved algorithm is proposed to overcome this shortage. The improved algorithm is used to analyze distribution of the similar pixel which gray level is similar to the target pixel within 8 neighborhoods of each pixel, then the candidate corner pixels are selected for following steps of Harris corner detection, thus the efficiency is highly improved.
