Color inconsistency is an urgent problem to be solved in stereoscopic video coding. In this paper, a robust color correction method for stereoscopic video coding is proposed. We first perform disparity estimation between right image and left image, and detect static scene between the current right image and the corrected right images, respectively. Next, spatial and temporal color correction matrices...
Three-dimensional video (3DV) technology is becoming increasingly popular, as it can provide high quality and immersive experience to end users. Huge amount of data for storage and transmission is an important problem to be solved. In this paper, an asymmetric MVC method is proposed. Color correction is first performed as a preprocessing step to provide consistent color information among views. Then,...
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...
Huge data for storage and transmission is an important problem to be solved in multi-view video application, such as interactive multi-view video. Up to now, many multi-view video coding methods have been proposed, in which different prediction structures are used in the directions of view and time. In this paper, by using color correction technique, a new multi-view video coding method is proposed...
In order to solve the problem of inconsistent color appearance between different views, and subsequently influences on multi-view video coding, a color correction algorithm of multi-view video based on depth segmentation is proposed in this paper. Firstly, depth information in each view is calculated. Then, background and foreground region are separated with the depth information. Finally, correction...
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...
Because of scene illumination or camera calibration, color appearance of the same object between different viewpoints may be different in multiview video system. Traditional illumination compensation algorithm for image is unable to solve this problem effectively. In this paper, a novel color correction method for multiview video system is proposed based on retinex color constancy theory. To eliminate...
Inconsistent color between different viewpoints is a serious problem in multi-view image processing. A multi-view image color correction method is proposed. We first estimate whether global correction satisfied for the target image and source image. If no global correction is satisfied, image segmentation and Karhunen-Loeve (K-L) transform are performed. Then, local mapping relations between target...
