Abstract
Image compression is accomplished by dividing an image into blocks which are encoded and compressed by finding similarities among the blocks. Image quality and speed are increased through several mechanisms such as varying the size of the blocks when image edges or test is present, by comparing the image blocks to prestored image patterns rather than other portions of the image, using raw data rather than compressed data under certain conditions and the use of inspection areas to increase the possibility of finding the most similar area quickly.
