An occurrence of occlusion is the challenge problem in stereo matching. In this paper, we propose a refinement algorithm of disparity maps with occlusion handling. In order to refine the disparity map, we obtain an initial disparity map with an optimization algorithm based on the modified constant-space belief propagation low complexity. An occlusion map is computed using unique constraint from...

Recent studies have shown that deep learning achieves superior results in the task of estimating 6D-pose target object from an image. End-to-end techniques use networks to predict pose directly image, avoiding limitations handcraft features, but rely on training dataset deal with occlusion. Two-stage algorithms alleviate this problem by finding keypoints image and then solving Perspective-n-Poi...

More than 50% of total energy consumed by the brain is utilized active transport processes which are responsible for keeping ionic homeostasis in brain. Under an ischemic condition, availability limited, and, as a result, inhibition ion pumps unavoidable. The initial consequence such gradual accumulation K+ extracellular space leading to second phase depolarization phenomenon. During depolariza...

Volumetric rendering is widely used to examine 3D scalar fields from scanners and direct numerical simulation datasets. One key aspect of volumetric rendering is the ability to provide shading cues to aid in understanding structure contained in the datasets. While shading models that reproduce natural lighting conditions have been shown to better convey depth information and spatial relationshi...

Recordings were made from single neurons in the hippocampus and parahippocampal gyrus while macaques were moved on a platform mounted on a free-moving robot or on wheels in a cue-controlled 2 m x 2 m x 2 m environment, in order to investigate the representation of space and of spatial memory in the primate hippocampus. The test conditions allowed factors that might account for spatial firing of...

Past studies of shape coding in visual cortical area V4 have demonstrated that neurons can accurately represent isolated shapes in terms of their component contour features. However, rich natural scenes contain many partially occluded objects, which have "accidental" contours at the junction between the occluded and occluding objects. These contours do not represent the true shape of the occlud...

We present a fast conservative from-region visibility method capable of handling 3D models using arbitrary 3D triangles as occluders. The from-region visibility problem is considered significantly harder than the from-point visibility problem, since it is inherently 4-dimensional. Our occlusion culling method is based on factorizing the 4D visibility problem into horizontal and vertical compone...
