Combined compression and simplification of dynamic 3D meshes

3D Segmentation, Compression and Wireless Transmission of Volumetric Brain MR Images

The main objective of this paper is to provide an efficient tool for delineating brain tumors in three-dimensional magnetic resonance images and set up compression-transmit schemes to distribute result to the remote doctor. To achieve this goal, we use basically a level-sets approach to delineating brain tumors in threedimensional. Then introduce a new compression and transmission plan of 3D br...

Multi-resolution modeling, visualization and compression of volumetric data

Due to the increasing complexity of volume meshes produced in many applications, multiresolution representations, simplification and compression have become key technologies for achieving efficient storage together with interactive modeling and visualization performance. View-dependent adaptive approximations can be extracted from multi-resolution representations enabling real-time isosurfacing...

3D Brain Tumor Segmentation Using Level-Sets Method

The main objective of this paper is to provide an efficient tool for delineating brain tumors in three-dimensional magnetic resonance images. To achieve this goal, we use basically a level-sets approach to delineating three-dimensional brain tumors. Then we introduce a compression plan of 3D brain structures based for the meshes simplification, adapted for time to the specific needs of the tele...

Perceptual Metrics for Static and Dynamic Triangle Meshes

Almost all mesh processing procedures cause some more or less visible changes in the appearance of objects represented by polygonal meshes. In many cases, such as mesh watermarking, simplification or lossy compression, the objective is to make the change in appearance negligible, or as small as possible, given some other constraints. Measuring the amount of distortion requires taking into accou...
