To meet the requirement of current bandwidth and storage facilities, it is required to further decrease the bitrate of 3D video content. This paper presents a scheme to partially filter different regions of the texture views and depth maps taking into account the characteristics of both of them. A combination of the distance of objects from the cameras and the spatial details of texture within the...
In this paper, we propose an adaptive downsampling pattern selection method for depth enhanced multiview video coding taking into account local characteristics of the depth map. The video content is divided into different stripes and a frequency-based measure is deployed to estimate the amount of degradation caused by downsampling and/or coding. The sampling pattern is determined for each vertical/horizontal...
A fundamental challenge of 3D video compression is to provide end users with a high quality video while respecting the limitations of available bandwidth or storage capacities. In this paper, a novel scheme is proposed to filter the texture pictures and depth maps partially targeting a lower bitrate for compression, while preserving the same subjective quality as the one achieved without filtering...
In this paper, we propose a content-adaptive pre-processing for downsampling depth map for 3D multiview plus depth video coding. The proposed scheme takes advantage of spatially varying content of depth maps and targets improved encoding performance. The key idea is to divide the video frames into several horizontal and vertical stripes and downsample each of them with an appropriate downsampling...
Multiview video plus depth (MVD) has proved to be a promising format enabling various 3D applications. One approach to achieve better MVD compression is to adjust the spatial resolution of depth map based on the content and the application. In this research two schemes are considered: first, multiview video coding accompanied by depth maps to improve the texture coding performance. Second, multiview...
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...
