A Roadmap to the Integration of Early Visual Modules

By examining the problem of image correspondence (binocular stereo and optical flow) and its relationship with other modules such as segmentation, shape and depth estimation, occlusion detection, and local signal processing, we argue that early visual modules are entangled in chicken-and-egg relationships, and unraveling these necessitates a compositional approach. In this paper, we present compositional algorithms which can match images containing slanted surfaces and images having different contrast, while simultaneously solving other problems as part of the same process. Ultimately, our goal is to motivate the application of the compositional approach to unify many other early visual modules. Experimental results have been presented on a large variety of stereo and motion images, including images with contrast mismatch and images containing untextured slanted surfaces.
