To make a matching algorithm to satisfy the requirements of high precision and anti-interference, a novel stereo-matching algorithm with efficient matching cost and adaptive guided image filter is proposed. Firstly, we adopt a modified Census transform with a local texture metric to compute the initial cost. It can make full use of the cross-correlation information between pixels. Meanwhile, we incorporate...
The original data of one view video is huge and that of multi-view video is much more. So, data compression is important for multi-views, and data compression is a key technology for multi-views. In this paper, we explore an efficient fractal video codec with multi-views. From the experimental results with the proposed method and other state of the art methods, we can conclude that the proposed algorithm...
Virtual view synthesis is the key technology of virtual reality and multi-view video system. Thus a new algorithm based on disparity estimation and interpolation is proposed in order to achieve intermediate view of any position between original images. A method of precise matching of every pixel based on block matching in the whole image is proposed in disparity estimation. And prediction work of...
Intermediate View Synthesis (IVS) is a key technology in multi-view display, and it is widely used in many fields, such as three dimensional (3D) television, 3D tele-videoconference, 3D video application, robot vision, virtual machine, medical surgery and so on. Disparity estimation is one of main methods of IVS. Some new intermediate view reconstruction techniques based on the adaptive disparity...
Virtual view rendering is one of the key techniques of interactive 3D video systems, and is analogue expression to the real world in virtual reality systems. This paper proposes a new algorithm of virtual view rendering between two views taken in the same scene at the same time, which is based on self-adaptive block matching disparity estimation. This algorithm outputs any view between the two origin...
A novel object-based fractal monocular and stereo video compression scheme with quadtree- based motion and disparity compensation is proposed in this paper. Fractal coding is adopted and each object is encoded independently by a prior image segmentation alpha plane, which is defined exactly as in MPEG-4. The first n frames of right video sequence are encoded by using the circular prediction mapping...
