Methods for depth-map filtering in view-plus-depth 3D video representation
View-plus-depth is a scene representation format where each pixel of a color image or video frame is augmented by per-pixel depth represented as gray-scale image (map). In the representation, the quality of the depth map plays a crucial role as it determines the quality of the rendered views. Among the artifacts in the received depth map, the compression artifacts are usually most pronounced an...
متن کاملDiscontinuity-adaptive depth map filtering for 3D view generation
A depth image-based rendering (DIBR) technique is one of the rendering processes of virtual views with a color image and the corresponding depth map. The most important issue of DIBR is that the virtual view has no information at newly exposed areas, so called disocclusion. The general solution is to smooth the depth map using a Gaussian smoothing filter before 3D warping. However, the filtered...
متن کاملView Synthesis using Depth Map for 3D Video
Three-dimensional (3D) video involves stereoscopic or multi-view images to provide depth experience through 3D display systems. Binocular cues are perceived by rendering proper viewpoint images obtained at slightly different view angles. Since the number of viewpoints of the multi-view video is limited, 3D display devices should generate arbitrary viewpoint images using available adjacent view ...
متن کاملMultiple-view Video Coding Using Depth Map in Projective Space
In this paper a new video coding by using multiple uncalibrated cameras is proposed. We consider the redundancy between the cameras view points and efficiently compress based on a depth map. Since our target videos are taken with uncalibrated cameras, our depth map is computed not in the real world but in the Projective Space. This is a virtual space defined by projective reconstruction of two ...
متن کاملDepth Map Discontinuity Correction for 3D Video Systems
Inaccurate depth map discontinuities are an important source of artifact and distortion in multiview systems and applications requiring depth-based view rendering such as 3DTV or free-viewpoint video. Such errors along depth discontinuities frequently occur during depth estimation and/or depth map coding. In this paper we present a novel method for correcting inaccuracies on the discontinuities...
