(English) Improving Border Localization of Multi-Baseline Stereo Using Border-Cut

mesh

Abstract This paper presents a novel algorithm that improves the localization of disparity discontinuities of disparity maps obtained by multi-baseline stereo. Rather than associating a disparity label to every pixel of a disparity map, it associates a position to every … Continue reading

(English) Geo-consistency for Wide Multi-Camera Stereo

icon-drouin-stereocvpr05

Abstract This paper presents a new model to overcome the occlusion problems coming from wide baseline multiple camera stereo. Rather than explicitly modeling occlusions in the matching cost function, it detects occlusions in the depth map obtained from regular efficient … Continue reading

(English) Automatic Relighting of Overlapping Textures of a 3D Model

Abstract This paper presents a new method to correct overlapping textures of a single 3D model where each texture was obtained under possibly different lighting conditions and color response of the camera. This situation arises frequently when a single object … Continue reading

(English) Cylindrical Rectification to Minimize Epipolar Distortion

iconroymeuniercoxcvpr97

Abstract We propose a new rectification method for aligning epipolar lines of a pair of stereo images taken under any camera geometry. It effectively remaps both images onto the surface of a cylinder instead of a plane, which is used … Continue reading
