This work concerns the compression of x-ray images of the breast using an original coding method based on a 2D wavelet transform. A tree-structured analysis/reconstruction system is used with Daubechies wavelet filters in order to decompose the original image into subbands; then we code only the low resolution subimage with the JPEG algorithm. This hybrid method has been compared with the JPEG approach, and results are proposed for different compression ratio.
