Because fingerprint image is composed of strip

it is difficult to increase compress ratio by tranditional fractal compress method based on block IFS. A new fractal compress method is presented. At first the image block data is formed into a serial data according to the direction of the strip. And then the data is coded by fractal image compress method in one dimension. The theory analysis and experiment results show that this approch can increase image compress ratio and improve the quality of the recovered image. At last a method to eliminate the block effect based on direction filte is presented.
