Abstract

This article presents the results of a partial implementation of the image compression standard recommended by the CCSDS, using parallel processing. The objective is to achieve a reduction in processing time of the Discret Wavelet Transform with the aid of a GPU. Through remote sensing images, the algorithm is tested and shows an acceleration around four times the performance of the float DWT used in the recommendation
