Color is very important in setting the style of images and video, but always influenced by internal and external imaging factors. For this reason, it is necessary to eliminate color inconsistence between viewpoints in multi-view imaging. In this paper, a color correction method for multi-view video is proposed based on color variation curve. In the proposed method, color variation curve is used to...
Multi-view video is a new multimedia service which provides interactive experience and depth perception. Color variations between the camera views are necessary to be eliminated in multi-view imaging. In this paper, a dominant color tracking based color correction method for multi-view video is proposed using Kalman filter. It tracks the dominant colors by using Kalman filter to fit the color variation...
Motion detection and extraction for multi-view video (MVV) is one of the key technologies for MVV applications, and it has become a hot in recent years. In this paper, a new method that will use semantic information and movement information based on depth maps for motion detection is pro-posed. First, a sequence of consecutive depth images is converted into a sequence of consecutive temporal-to-spatial...
Region-of-interest (ROI) in multiview video (MW) is different from that of conventional single view video because MW provides three-dimensional perception and makes people more interested in depth discontinuity and pop-out regions. In this paper, we define a novel depth perceptual ROI for MW and discuss four ROI extraction schemes according to temporal and inter-view correlation of the MW. Then, depth...
Compared to traditional multi-view systems, client-oriented multi-view video system could significantly simplify the complexity at the client since part of disparity estimation is left to the sever. This paper proposes a fast disparity refinement algorithm for the client-oriented multi-view video system. Firstly, the coarse disparity map is generated by adopting 8times8 block based disparity estimation...
Free-viewpoint video (FVV) system is a new kind of multimedia in the coming future. Intermediate image rendering plays an important role in FVV system and needs to be solved. So far, the intermediate image rendering methods are not suitable for real-time FVV due to the computational complexity. This paper presents a temporal correlation based intermediate image rendering method to accelerate the processing...
A content-adaptive color correction algorithm for multi-view video is proposed due to variation in lighting or camera parameters. We first establish color correction property between the target image and source image. Then color correction matrix can be obtained by global correction or preferred region matching correction. Finally, video tracking technique is used to correct multi-view video sequences...
In stereo video communication over the Internet, video quality is always not guaranteed since packets losses always occur. The loss of packets may result in the loss of a whole right video frame. To deal with such a case, an error concealment algorithm for whole-right-frame losses in stereo video, which is based on relativity analysis, is proposed in this paper. It chooses different information to...
