.The accuracy of color (Bit Depth), then the program will prepare the image before processing is the quality (Image Enhancement) suitable for the job. Such as to improve the quality of data. On the scope of objects on a picture and reduce the noise of the image, the contractThis process will choose to use a mean Filter image filter is filtering image data using the average math. This method will bring the light intensity of point matching in the sort (sort), from least to most.If the total number of images is an even number. The two in the middle will bring the average. In this way, reduce noise. Images can be reduced noise, if have image size N × M all K images can calculate the new image by using equation (1)
