Abstract

Knowing that, the computing process of the S. Mallat Transform algorithm is characterized by a purely sequential structure, and from the fact, the on line mode arithmetic is more suitable for the computation of this kind of operations. We propose in this paper, a new wavelet Transform algorithm and a suitable architecture implemented on a Xilinx FPGA circuit. In this study, we will show how on line arithmetic is used to implement a pipelined architecture of the S.Mallat Transform and we will demonstrate through different implementations under different medical image and different computation mode that it might be used successfully for medical image compression.
