Abstract : In this paper, a novel lossless compression method for volumetric medical datasets based on 3D adaptive prediction is presented. While almost all existing methods are based on a three-dimensional wavelet transform, this method, referred to as OLP-3D, evaluates the performance of an algorithm that operates on a least-square prediction basis. This leads to a different method with approximately similar results on compression performance, although with some advantages on computational cost.
