Image processing technology is improving lately, and its importance has been greatly increased. Therefore, a lot of research and work is utilized with an image processing. For individual use, just need the effective and swift method simply process the image and make out the result immediately; while for research, it usually use more accurate and complex method for particular purpose, can somewhat tolerate the time cost and huge operands. Everyone has advantage and disadvantage; everyone deserves to be delved into. By the way, in any high level algorithm, they still take important parts in actual application. This paper contains some simple daily used and research used complex methods, describe their theories and analysis implement results, for deeper comprehension. This paper, we introduced the representative method of Gaussian smoothing technique, Laplace sharpening technique, Canny edge detection technique. After that, take an actual application of car license location, elaborate the common algorithm responsibility, and meanwhile take some subtle new attempts for algorithm development. In the experiment, the results for each algorithm showed by image and describe the characteristics for each algorithm.
