Abstract:
This paper presents a new algorithm for stereo matching which makes use of simultaneous matching, surface reconstruction, and segmentation of world surfaces. By integrating these three phases, which are traditionally temporally separated, the algorithm can make use of the current surface information to help disambiguate the potential matches. After discussing the required mathematical background, the paper describes the integrated process of matching, reconstruction and segmentation. Unlike past attempts at integrating these processes, the presented algorithm uses a single smoothness criterion for both matching, reconstruction and segmentation. The segmentation part of the process is based on estimates of surface bending energy, and is significantly different from previous segmentation algorithms. Examples are presented showing results on both synthetic images and camera acquired images. The camera-based examples include both a traditional type scene with two objects, and a scene with transparent objects.
