Hypercolumn-based stereo correspondence

Geometry of Contour-based Correspondence for Stereo

We consider the problem of computing stereo correspondence for scenes dense in physical structure, such as a bouquet of flowers. Boundaries are then space curves, formally governed by the projective geometry induced by the stereo camera configuration and by the differential structure of the curves in the scene. We propose that the correspondence problem can be solved by relating the differentia...

Window-based approach for fast stereo correspondence

In this study, the authors present a new area-based stereo matching algorithm that computes dense disparity maps for a real-time vision system. Although many stereo matching algorithms have been proposed in recent years, correlation-based algorithms still have an edge because of speed and less memory requirements. The selection of appropriate shape and size of the matching window is a difficult...

Multispectral Stereo Image Correspondence

This paper presents a novel multispectral stereo image correspondence approach. It is evaluated using a stereo rig constructed with a visible spectrum camera and a long wave infrared spectrum camera. The novelty of the proposed approach lies on the usage of Hough space as a correspondence search domain. In this way it avoids searching for correspondence in the original multispectral image domai...

Stereo Correspondence Using Moment Invariants

Stereo correspondence using segment connectivity

This paper presents a method to search for stereo correspondence based on the connectivity of segments. The data structure is defined by boundary representation. The free curve can be treated by this data structure not as a straight line approximation, but as a curved line. Some candidates for correspondence pairs consist of two segments in left and right images under epipolar condition. The co...
