Abstract
This paper deals with the implementation of 3D wavelets techniques for compression of medical images, specifically in the MRI modality. We show that at the same compression rate a lower loss of information can be obtained by using fully 3D wavelets as compared to iterated 2D methods. An adaptive thresholding step is performed in each sub-band and a simple Run Length Encoding (RLE) method for compression is finally used. A reconstruction algorithm is then implemented and a comparison study of the reconstructed image is then proposed, showing the high performance of the proposed algorithm.
