Although Time-of-Flight (TOF) camera can provide real-time depth information from a real scene, the resolution of depth map captured by TOF camera is rather limited compared to HD color cameras, and thus it cannot be directly used in 3D reconstruction. In order to handle this problem, this paper proposes a novel compressive sensing (CS) based depth map super-resolution method, which transforms a low...
In this paper, an efficient depth image based view rendering method for high quality multiview virtual images synthesis is proposed, which utilizes two color images with their associated depth maps. The proposed method consists of four main steps. The first step is virtual camera parameters design by using shift-sensor camera model to avoid the keystone distortion. Secondly, the mixed color pixels...
With the development of display hardware, computing power, transmission and rendering algorithm, 3DTV is becoming the most promising technology that provides the users a more natural viewing experience than 2D displays. But most 3D movies need to wear 3D glasses to watch. Naked eye 3D is the ultimate goal of the development of 3D technology. Multi-view rendering by depth image based rendering (DIBR)...
Recent computer vision technology has made great progress in 3DTV industry. The advent of 3DTV to the home raises a number of challenges beyond the basic display of an available stereo pair. One of them is the production of 3D augmented contents. To present virtual objects over the real world, the existing method is offline processing in postproduction. It is a difficult and expensive work since flexible...
Depth generation is a key technology in computer vision. Known methods mainly rely on stereo matching, or measuring devices like ToF camera. The ToF camera performs well in low-textured regions and repetitive regions where stereo matching fails. In contrast, stereo matching works better than ToF camera in textured regions. Based on their complementary characteristics, we introduce a method to combine...
This paper focuses on the near real-time implementation of end-to-end 3DTV System. It is specially designed for the generation of high-quality disparity map and depth-image-based rendering (DIBR) on the graphics processing unit (GPU) through CUDA (Compute Unified Device Architecture) API. We propose our novel methods including a kind of stereo matching with adaptive windows and an asymmetric edge...
