Improvement of the compression JPEG 2000 quality by Denoising Filters

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 study, we use standardfilters that permits to remove some details of the image and to reduce 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 will have a great impact on storage and transmission.
