Advances in 3D video technology expand the availability of hardware for 3D video generation and display. Some 3D capture and coding arrangements take advantage of a mixed resolution setup. In difference to typical 3D multiview video the mixed resolution scenario assumes that a subset of views is coded at reduced spatial resolution. After decoding, the low resolution views have to upsampled in order...
The multiview-video-plus-depth (MVD) format selected for 3D video standardization describes 3D scene by video and associated depth and enables generation of virtual views through the depth-image-based rendering (DIBR) process. The Kinect™ sensor is equipped with a red-green-blue (RGB) camera and a depth sensor and it is suitable to capture synchronous video and depth streams. However, these sensors...
Recent developments of three-dimensional (3D) video coding greatly rely on the use of Multiview Video plus Depth (MVD) data format for representing a 3D scene. This type of data can be coded with conventional video compression schemes and can enable advanced 3D video functionality, such as rendering of virtual views at the decoder side. The MVD represents a 3D scene from different viewing angles as...
Depth maps, an essential part in the new generation of 3D video coding, allow rendering of arbitrary viewpoints of a video scene. Depth maps are characterized by sharp object boundaries, which significantly affect the rendering quality and account for the most bitrate for depth map coding. This paper proposes a novel intra coding method for depth maps based on a two-step adaptive boundary location...
In the multiview video plus depth (MVD) representation for 3D video, a depth map sequence is coded for each view. In the decoding end, a view synthesis algorithm is used to generate virtual views from depth map sequences. Many of the known view synthesis algorithms introduce rendering artifacts especially at object boundaries. In this paper, a depth-level-adaptive view synthesis algorithm is presented...
Several quality evaluation studies have been performed for video-plus-depth coding systems. In these studies, however, the distortions in the synthesized views have been quantified in experimental setups where both the texture and depth videos are compressed. Nevertheless, there are several factors that affect the quality of the synthesized view. Incorporating more than one source of distortion in...
