This work presents the use of a simple labroatory-designed DIP for executing several digital image processing algorithms. These algorithms include image enhancement and restoration, geometrical corrections and zooming, feature extraction, and others. The system used comprises, in addition to the microcomputer, a digital memory system capable of acquiring and storing up to four images. Each image is stored in a square format of 256x256 pixels x 6 bits. The theory , flow charting, and assembly language programs for some chosen algorithms are presented.
