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… (More)
Bitstream parsing is a basic task in video decoding systems. With the development of video compression standards, the trend of the VLSI architecture for bitstream parser is toward programmable. Due to the strong data-dependency and bit-level sequential operations, bitstream parsing is unsuitable to accelerate by general architectures, such as RISC, SIMD and… (More)
This paper proposes an efficient SIMD architecture with parallel memory for 2D cosine transforms of multiple video standards. A novel parallel memory scheme is employed to provide conflict-free parallel access in both horizontal and vertical directions with the successive or even/odd mode, as well as to eliminate data permutation and matrix transposition.… (More)
An algebra proposed for current-mode CMOS multivalued circuits is briefly reviewed. This paper discusses its application in the design of multivalued circuits. Several current-mode CMOS quaternary and quinary circuits are designed by algebraic means. The design method based on this algebra may offer a design simpler than the previously known ones.
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.… (More)
This paper proposes a mapping method simplifying the Reed-Muller expansion (“RM expansion”) of a ternary function under fixed polarities and the transformation of the RM expansion coefficients with different fixed polarities.
