E. Digital Image Processing (Forth Edition). 令(r_k, k = 0, 1,2, cdots, L-1) 表示图片密度值为(k), [h(r_k) = n_k, : k = 0, 1, cdots, L-1, ] 整个图片(f(x, y))中密度值为(r_k)的pixel的数量, 定义概率 [p(r_k) = frac{h(r_k)}{MN} = frac{n_k}{MN},...
In digital image processing, the SSD is a measure of the similarity between image blocks. It is calculated by taking the square of the difference between each pixel in the original block X (a portion from the current frame) and the corresponding pixel in the Y block being used for ...

A problem in digital image processing employing a tone reproduction function that maximizes the quality of the processed image is to automatically determine the overall contrast of the processed image. In an improved method for determining the contrast of the processed image, the contrast is automatica...
