Most of approaches to salient object detection focused on two-dimensional images, while rare attention was attached to the light field which can provide exclusive visual information for salient object detection and other computer vision applications. An effective algorithm of salient object detection is proposed for light field data. First, boundary connectivity is calculated on all-focus image. Then,...
During the depth image based rendering (DIBR), depth map is a new type of video sequence to be compressed. The synthesized result of DIBR is highly related to the quality of the depth map. Depth map also has some new features than color maps. It occurs to us that some improvement is required. Higher efficiency and keeping the edge quality is two critical issues for depth compression. In this paper,...
Depth map coding is a new topic in multiview video coding (MVC) following the development of depth-image-based rendering (DIBR). Since depth map is monochromatic and has less texture than color map, fast algorithm is necessary and possible to reduce the computation burden of the encoder. This paper proposed difference detection based early mode termination strategy. The difference detection (DD) algorithms...
