We propose and evaluate a number of novel improvements to the mesh-based coding scheme for 3-D brain magnetic resonance images. This includes: 1) elimination of the clinically irrelevant background leading to meshing of only the brain part of the image; 2) content-based (adaptive) mesh generation using spatial edges and optical flow between two consecutive slices; 3) a simple solution for the aperture problem at the edges, where an accurate estimation of motion vectors is not possible; and 4…

Reversible interframe compression of medical images: a comparison of decorrelation methods.

Whether data representing medical image sequences can be compressed more efficiently by taking into account the temporal correlation between the sequence frames is investigated, with results that suggest interpolation-based methods are superior to extrapolation- based methods, and estimation of interframe motion is not advantageous for image compression.

An occlusion-adaptive forward-tracking mesh model, where connectivity of the mesh elements (patches) across covered and uncovered region boundaries are broken, enables better rendition of the motion, while tracking is necessary to avoid transmission of all node locations at each frame.
