Description: Based on this one-dimensional analysis, the theory can be carried over to two-dimensions as long as there is an accurate approximation to calculate the derivative of a two-dimensional image. The Sobel operator performs a 2-D spatial gradient measurement on an image. Typically it is used to find the approximate absolute gradient magnitude at each point in an input grayscale image. The Sobel edge detector uses a pair of 3x3 convolution masks, one estimating the gradient in the x-direction (columns) and the other estimating the gradient in the y-direction (rows). A convolution mask is usually much smaller than the actual image. As a result, the mask is slid over the image, manipulating a square of pixels at a time.

Description: 灰階(gray-scale)圖像處理(60*60 pixel)controller控制各個程式的地址以及開關，input_mem將資料讀進記憶體，grayscale將讀取資料像素的亮度以數值來表示，將24bit的 像素化成四個8bit的值輸出。接著進入sobel，在此將前面的四個值乘上1或-1個別的相加，得出新的四個值，輸入進shiftcase進行threshold的判斷，大於threshold則表現出白色(255)，小於threshold則表現出黑色(0)，最後將結果存入記憶體out_mem。//Verilog-Implement digital image processing through HDL.
