Physics-Based Segmentation : Looking Beyond Color

We previously presented a framework for segmentation of complex scenes using multiple physical hypotheses for simple image regions. A consequence of that framework was a proposal for a new approach to the segmentation of complex scenes into regions corresponding to coherent surfaces rather than merely regions of similar color. Herein we present an implementation of this new approach and show example segmentations for scenes containing multicolored piece-wise uniform objects. By using this new approach we are able to intelligently senwent scenes with objects of greater complexity than previous physics-based segmentation algorithms. The results show that by using general physical models we can obtain segmentations that correspond more closely to objects in the scene than segmentations found using only color.
