Subjective quality evaluation is the basis of quality evaluation of stereoscopic images. As the lack of a public and diverse testing database currently, in this paper, a symmetric stereoscopic images database is built. And then the subjective quality of stereoscopic images is analyzed from two aspects, one is the effects of JPEG, JPEG2000, H.264. The other is the comparisons between symmetric and...
With the development of three dimensional media resources, the corresponding intellectual property protection problem also occurs. In this paper, a blind stereoscopic image watermarking algorithm based on the relationship modulation is proposed. Firstly, the original stereoscopic images are divided into non-overlapping blocks respectively, and the polarity of these blocks in left and right images...
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...
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...
The macroblock mode distributional proportion and rate distortion (RD) cost of every macroblock mode are analyzed in detail. Then, concept of integrated optimal macroblock mode is introduced. The RD performance of integrated macroblock mode being the encoding macroblock mode is discussed theoretically. Finally, a fast macroblock mode selection algorithm based on macroblock mode analyses is proposed...
