Hole-filling based on disparity map for DIBR
Due to sharp depth transition, big holes may be found in the novel view that is synthesized by depth-image-based rendering (DIBR). A hole-filling method based on disparity map is proposed. One important aspect of the method is that the disparity map of destination image is used for hole-filling, instead of the depth image of reference image. Firstly, the big hole detection based on disparity ma...
متن کاملDepth-Aided Exemplar-Based Disocclusion Filling for DIBR View Synthesis
Depth-image-based-rendering (DIBR) is a popular method of synthesizing new views of scenes using traditional images accompanied by depth maps. However these new view suffer from disocclusion holes ‒ background areas revealed by the viewpoint change which have no image or depth data. The filling of disocclusion holes has been an area of development since 2011. This paper seeks to further develop...
متن کاملHole Filling with Multiple Reference Views in DIBR View Synthesis
Depth-image-based rendering (DIBR) oriented view synthesis has been widely employed in the current depth-based 3D video systems by synthesizing a virtual view from an arbitrary viewpoint. However, holes may appear in the synthesized view due to disocclusion, thus significantly degrading the quality. Consequently, efforts have been made on developing effective and efficient hole filling algorith...
متن کاملHole-filling Based on Disparity Map and Inpainting for Depth- Image-Based Rendering
Due to the changes in viewpoint, holes may appear in the novel view synthesized by depth-image-based rendering (DIBR). A hole-filling method combining disparity-mapbased hole-filling and inpainting is proposed. The method first eliminates matching errors in destination image according to the disparity map. Then, holes are classified into different types according to their sizes. Finally, a disp...
متن کاملAn overview of free viewpoint Depth-Image-Based Rendering (DIBR)
3D Video has caught enormous attention in consumer market due to the progress in technical maturity of 3D displays, digital video broadcasts and computer vision algorithms. Video-plus-depth representation makes the concept of free viewpoint video feasible allowing the user to freely navigate within real world visual scenes. In this paper, we review the existing methodologies and 3D video proces...
