Abstract :
In this paper, we introduce a new image compression scheme that involves three steps: first a multiresolution decomposition of the images is performed using the Wavelet Transform (WT). A thresholding algorithm is then used for the wavelet coefficients. Finally, the coefficients derived are vector quantized using the LGB or the Compressed Maximum Descent (CMD) algorithm
