【摘要】 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.更多还原

【Abstract】 Harris corner detection is based on the pixel gradient of the image,which is restricted to the relativities 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.The relationship between image quality and Harris corner detection was proposed.The image quality was taken as a gist of the parameter choosing of Harris corner detection.In addition,it is suggested that the corner detection can be put in practice by choosing different parameters of the image with different qualities based on the evaluation scales.更多还原
