PJPEG2000

The aim of this paper is to improve the performances of the JPEG2000. In fact, the approach named PJPEG2000 consists in inserting a phase of pretreatment before initiating the JPEG2000 process. This investigation allows better quality compression. When compressing images, noise is fatal to compression performance, it can be both annoying for the observer and make transmission of the imagery consume excessive amounts of bandwidth. The pretreatment based on the filtering reduces noise and thus improve both visual impression and transmission properties. The comparison between JPEG2000 and PJPEG2000 shows that the latter is favourable in both PSNR and WPSNR and in visual inspection evaluation.
