Abstract: Nowadays，with the rapid development of the information society，image has become one of the important carriers which can transmits information.Because of the massive content of information of unprocessed image，it is extremely important to try our best to research and develop the technology for image coding.This main topic is to explore for a large area of continuous shadow of the same color or image compression.We use quarter-tree decomposition of image compression methods to image compression because of the deficiencies of the RLE algorithm.Experiment indicates that the improved technique which uses quarter-tree decomposition of image compression methods can greatly improve compression efficiency.The technique presents a new approach for the technique of static image compression.

Key words: image compression, quarter-tree decomposition, run-length-encoding
