A new surface/volume rigid registration method is proposed that allows fast and robust convergence. In this works, rigid bodies are modeled usind a matrix of voxels and its associated compressed voxel representation (V-rep.). The two models are fused to obtain an indication of the quality of the match. Optimization techniques using gradient descent and/or genetic algorithms are implemented to select the appropraite transformations, where the search space is established. A sequence of translations and rotations are applied to one of the models until an appropriate match is reached through this space search. Unique data structures are introduced to efficiently store the data. The method and an experimental computer code are demonstrated in the paper.
