....good image quality and have generated much interest in the scienti c community as competitors to DCT based compression schemes. With the nalization of the wavelet based JPEG2000 standard [13] and the inclusion of a wavelet al..gorithm for synthetic natural hybrid coding in MPEG 4 (MPEG 4 VTC) [12, 5] there is no doubt left that wavelet image compression has to be considered state of the art nowadays. In this work, we discuss the parallelization of the MPEG 4 Visual Texture Coding (VTC) standard. The reference software used for our parallelization is the MPEG 4 MoMuSys Veri cation Model of ....

....when image data is subband coded and sent by UDP. Existing loss concealment schemes are performed in the sender side, or in the receiver side, or in both sides. Sender side loss concealments of coded images consist of layered coding and multiple description coding (MDC) methods. Layered coding [1] partitions an image into a base layer with visually important image data and a few enhancement layers. In networks with priority support, the base layer is normally assigned a higher priority so that it has a larger chance to be delivered error free. However, layered coding is not applicable in ....

....They are usually more e#ective because receivers can convey information on losses and reconstruction methods to senders in order for senders to better adapt its control. There are two popular ways to facilitate such recovery: layered coding and multi description coding (MDC) In layered coding [9], data is partitioned into a base layer and a few enhancement layers. The base layer contains visually important image data that can be used to produce outputs of acceptable quality, whereas the enhancement layers contain complementary information that allows higher quality image data to be ....

....and image coding, namely MPEG 4 [2] and JPEG 2000 [4] has led to exponentially increased interest about coding techniques for the wavelet transform coefficients. The waveletbased coding techniques adopted by the two standards are the inter subband, wavelet tree coding of wavelet coefficients [12] and the intra subband, wavelet block coding [14] In this paper, the main focus will be on the wavelet tree coding approach, which exploits the parent children dependencies inherent in the dyadic tree organization of a wavelet transform (Figure 1) Various authors, for example [8] 11] 16] ....
