Abstract

The discrete wavelet transform (DWT) has recently been proved a powerful tool for image compression because of its multiresolution decomposition aspect. However, this algorithm takes high computation time, so it is necessary to use a parallel computer to compress 6000 X 6000 satellite images in real time. This paper deals with the parallelization of the image compression algorithm based on DWT. We present implementation results on several parallel computers (CM5, CM200, OPENVISION, SYMPHONIE).
