Correspondence as energy-based segmentation
We pose the correspondence problem as one of energy-based segmentation. In this framework, correspondence assigns each pixel in an image to exactly one of several non-overlapping regions, and it also computes a displacement function for each region. The framework is better able to capture the scene geometry than the more direct formulation of matching pixels in two or more images, particularly ...
متن کاملSegmentation-Based Adaptive Support for Accurate Stereo Correspondence
Significant achievements have been attained in the field of dense stereo correspondence by local algorithms based on an adaptive support. Given the problem of matching two correspondent pixels within a local stereo process, the basic idea is to consider as support for each pixel only those points which lay on the same disparity plane, rather than those belonging to a fixed support. This paper p...
متن کاملForeground and Shadow Segmentation Based on a Homography-Correspondence Pair
A static binocular camera system is widely used in many computer vision applications; and being able to segment foreground, shadow, and background is an important problem for them. In this paper, we propose a homography-correspondence pair-based segmentation framework. Existing segmentation approaches, based on homography constraints, often suffer from occlusion problems. In our approach, we tr...
متن کاملTeager Energy Based Blood Cell Segmentation
A new method for fast and simple segmentation of peripheral blood smears using Teager energy operator (TEO) is presented. The two-pan algorithm efficiently segments leucocytes present in the smear into nucleus and cytoplasm. The local mean weighted high pass filtering property of Teager energy operator is used to identify and distinguish the nucleus of white blood cells. Cytoplasm present in th...
متن کاملPre-attentive segmentation and correspondence in stereo.
Traditional stereo grouping models have focused on the problem of stereo correspondence between monocular inputs. Recent physiological data revealed that the disparity selective V2 cells increase their responses when (random-dot stereograms) stimuli within their receptive fields are at or near the boundary of a depth surface. Such highlights to depth (non-luminance) edges are seemingly not comp...
