摘要
本文提出1种新的基于像素均值的图像边缘评价函数。以边缘为基准,在边缘的两侧取一定范围内的像素均值的函数。实验把此函数和常用的图像降噪质量指标NMSE进行对照。实验表明两种图像评价函数的评定结果基本相同,这种基于像素均值的图像边缘评价函数是可行的。
This paper advance a new evaluation function of the image edge base on pixel average value.Edge as the benchmark,pixel average value was taken within certain scope of both sides of the image edge.The experiment compared this function with NMSE of image.The results show,the result of the two image evaluation function are same,this evaluation function of the image edge base on average pixel value is feasible.
