چکیده:

This paper proposes an object-based, highly scalable, lossless coding approach for MRI data. The proposed approach, called OBHS-SPIHT, encodes each slice of the input MRI data set separately in a multiresolution fashion from low resolution to full resolution without losing any information. To achieve more compression efficiency, the algorithm only encodes the main object of interest in the input data set, and ignores the unnecessary background. The experimental results on some test MR image sets show the efficiency of the proposed algorithm for multiresolution lossless coding. OBHSSPIHT, is a very attractive coding approach for medical image information archiving and transmission applications.
