Abstract
In this paper, we introduce a new fuzzy technique, information matrix, to compress images. With high compression speed, this fuzzy technique has compression ratio more than 50% for any original image and the reconstructed image quality is good, although not exactly as the same as the original image. In this paper we give two examples to show the compression ratio and the reconstructed image quality. One is a curve with 100 points. We compress this image with 20 rules. The compression ratio is 79%. Another is a colour picture with flowers. The compression ratio is 50%.
