Abstract

For communication and storage efficiency, image data should be substantially compressed. The compression ratio is limited by noise, which degrades the correlation between pixels. Noise can occur during image capture, transmission or processing, and may be dependent on or independent of image content. In this paper, we use standard filters that permit the removal of some details of the image and the reduction of all possible noise. After filtering, the image is compressed with JPEG2000. By discarding the noise, the compression ratio can be improved. This method was verified using 30 images. This technique can increase the ratio without significantly affecting the image quality. This process has a great impact on storage and transmission
