Natural textures like grass, water, sand etc. contain large amount of visual details that consume a lot of bitrate while compressing it, but in fact such details are irrelevant for the human vision. Therefore, exploiting human perception properties could provide better compression of such data. In this paper we propose two novel schemes for identifying and(More)
In this paper, we propose a novel freeview generation system. We first discuss the problem of misalignment of the edges between color frame and depth frame, and propose an optimization method to solve it. Then an original frame is separated into two parts, depending on the sizes of the resulting dis-occluded areas in the virtual view. Illumination changes(More)
High quality view generation and interpolation is a crucial problem for the success of 3D video systems. It is known that interpolation artifacts especially occur along object boundaries where depth values fluctuate. We therefore present a novel view interpolation algorithm that introduces specific processing without producing any geometric distortion. The(More)
Visual textures like grass, water etc. consist of dense and random variations in contrast that are perceptually indistinguishable by a human eye. Such textures are costly to encode using image and video codecs. For example, in the state-of-the-art compression standard High Efficiency Video Coding (HEVC), detailed textures typically show relatively strong(More)
