This paper proposes a novel prediction scheme for depth map coding. We utilize the fact that depth values are largely dependent on objects and one small block consists of only a small number of objects at most. The proposed method approximates each block with one palette and one object shape map. The palette consists of two representative depth values for(More)
Video with depth is attracting attention as a promising approach to future 3D video. Unlike conventional video coding technologies, video with depth should take the correlations between video and depth into account. This paper proposes a novel bi-prediction scheme for video coding that exploits the structure similarity between video and depth. In the(More)
Pixel domain methods for content-aware image retargeting have a performance limitation in that they distort important objects when an image is shrunken too much. To address this problem, we have designed and developed a novel 3D space domain image retargeting which rearranges objects with occlusions and deforms objects. With this method image formation is(More)
This paper describes a large-scale 3D magnetostatic analysis using the Domain Decomposition Method (DDM). To improve the convergence of an interface problem of DDM, DDM based on the Conjugate Residual (CR) method or the MINimal RESidual (MINRES) method is proposed. The CR or MINRES method improved convergence rate and showed stable convergence behavior in(More)
In anime production, some key-frames are drawn by artist precisely and then a great number of in-betweening frames are drawn by assistants' hands. However, it is seriously time-consuming and skilled work to draw many characters especially including face rotation. In this paper, we propose an automatic in-betweening technique for rotating face of hand drawn(More)
Heparin is used as an anticoagulant drug. The anticoagulation process is mainly caused by the interaction of heparin with antithrombin followed by inhibition of anticoagulant factor IIa and factor Xa. The anti-factor IIa and anti-factor Xa activities of heparin are critical for its anticoagulant effect; however, physicochemical methods that can reflect(More)
In 3D video compression, depth map is normally compressed by resolution reduction. To avoid artifacts in views synthesized with the reduced resolution depth map, up-sampling approaches based on special properties of depth map have been proposed. Most previous studies do not apply rate-distortion control and the quality of depth map and synthesized views is(More)
