There has been no fixed rule of pre-processing course required to do image processing that it was barely possible to find the proper pre-processing course, only to process with experience till now.
In this paper, lots of application method of pre-processing algorithm, only available by the non-typified and experiential method, shall quantify and the algorithm method of algorithm according to the rule shall calculate the frequency of the value of each pixel gray level and the histogrm of the image. And then average it to all pixel number and finally set a high-ranking or optional % standardized by the average value in teh standard value.
The result of a experiment showed the Median filter is superior to the Mean filter in all image of the smoothing filter. The sobel filter extracted feature. The laplacian filter presented sectional feature which not showed in original image.
