High performance JPEG 2000 and MPEG-4 VTC on SMPs using OpenMP
JPEG 2000 and MPEG-4 Visual Texture Coding (VTC) are both wavelet-based and state of the art in still image coding. In this paper we show sequential as well as parallel strategies for speeding up two selected implementations of MPEG-4 VTC and JPEG 2000 using the popular shared memory programming paradigm OpenMP. Furthermore, we discuss the sequential and parallel performance of the improved versions and compare the efficiency of both algorithms.
