-Program code shows the image using Prewitt edge detection operator with different σ values LoG image edge detection operator Canny edge detection using the edge of the image threshold segmentation of the image threshold method of water line segmented image of the matrix quadtree decomposition text and the image is divided into two categories of non-text binary image morphological gradient edge detection of morphological instance- the image from the PCB to remove all the current lines, retaining only the object chip
