In this paper, we introduce a novel approach to bas-relief generation and shape editing that uses gradient-based mesh deformation as the theoretical foundation. Our approach differs from image-based methods in that it operates directly on the triangular mesh, and ensures that the mesh topology remains unchanged during geometric processing. By implicitly deforming the input mesh through gradient manipulation,...
This paper presents an inter-view motion prediction technique for efficient compression of motion vectors of the depth views in 3D-HEVC. 3D-HEVC is an extension of HEVC standard for coding the multi-view video plus depth content, known as MVD. In MVD format, the motion characteristics of the adjacent views in the depth video are highly correlated. In this paper, we take benefit of this correlation...
Advanced residual prediction (ARP) is an efficient coding tool in 3D extension of HEVC (3D-HEVC) by exploiting the residual correlation between views. In the early version of ARP, when current prediction unit (PU) has a temporal reference picture, a reference block is firstly identified by a disparity vector and the residual predictor is then produced by aligning the motion information associated...
This paper presents a novel inter-view motion prediction technique used in 3D-HEVC which provides efficient compression for motion vectors. The 3D extension of HEVC (High Efficiency Video Coding) namely 3D-HEVC is under development in JCT-3V for coding multi-view video and depth data. Inter-view motion prediction takes benefit of the inter-view correlation between views by inferring the motion information...
3D-HEVC incorporates advanced inter-view prediction techniques based on more accurately derived disparity vector to better exploit the correlation between objects in different views. The efficient disparity vector derivation method, namely, Neighboring Block based Disparity Vector Derivation (NBDV) provides disparity without accessing any depth information. The NBDV has been developed as a part of...
Advanced residual prediction (ARP) is an efficient tool for 3D video coding by exploiting the residual correlation between views. In ARP, the residual predictor could be efficiently produced by aligning the motion information at the current view for motion compensation in the reference view. On the other hand, such on-the-fly residual predictor derivation process increases the complexity significantly...
