Harris 角点检测计算的依据是图像像素点的梯度,并且受约于像素之间的相关性. 而图像质量直接影响像素

之间的相关性,从而对Harris 角点检测产生作用. 本文根据图像质量的几个标准分别对图像进行评价,并阐述图像

质量和Harris 角点检测之间的关系,把图像质量作为Harris 角点检测选择参数的一个依据,并建议通过量表对不

同质量的图像选择不同的参数进行角点检测.-Harris corner detection is based on the pixel gradient of the image , which is restricted to the relativ2

ities between the pixels. Image quality affects the Harris corner detection , because of its direct influences on

the relativities between the pixels. The image was evaluated based on several certain imaging standards.
