First approach to context-aware segmentation

In a first approach to context-aware segmentation (CAS), I have implemented a prototype that uses spherical harmonics descriptor and cord-and-angle histogram to estimate similarities between segments. This prototype decomposes all models in a given collection according to all others. Bellow is an example of a model extracted from the PRECISE Engineering Shape Benchmark and decomposed along with others from this benchmark using the CAS approach.
