Module Description

The Mesh Compression (MC) module deforms the input tetrahedral mesh towards the boundaries of the input labeled image. Two point sets are extracted for the mesh deformation. The first (source point set) consists of the surface vertices in the input mesh. The second (target point set) consists of the surface edge points in the input labeled image. After the extraction of the two point sets, the input mesh is deformed by registering the source to the target point set using a Physics-Based Non-Rigid Registration method. The current version of the module supports a single-tissue labeled image and mesh.

Panels and their use

Mesh Generation Parameters: Size: Controls the size of the mesh. The smaller the value the larger the mesh. Value should be between [1,20] (default: 8). Fidelity: Controls the subdivision of the elements that belong to more than one image labels. The larger the value the better the conformity of the mesh on the image label boundaries. Value should be between [0.1,1] (default: 0.8). Resample Resolution: Controls the image resampling. Suggested value is 0 (no-resampling) for large tissues and 1 or 2 for smaller tissues. Value should be 0 or 1 or 2 (default: 0). Input/Output: Labeled Image: The input labeled image. Output Mesh: The output tetrahedral mesh in vtk file format. (default: outputMesh.vtk)
