3D cinema to 3DTV content adaptation

3D Video Rendering Adaptation: A Survey

“…However, the uniform disparity transform is not always appropriate for all pixel pairs in stereoscopic video. So the refined perpixel disparity transform, such as per-pixel depth correction and adjustment over the stereo images [23] is more preferred. Moreover, in the disparity transform, the occlusion problem [61] due to multiview geometry needs to be particularly processed to avoid the seriousness of pixel correspondence ambiguity among stereoscopic video.…”

“…When viewing 3D content from 3D cinema to 3DTV, the disparity transform is needed to adjust depth range besides the width resizing [23]. Since the viewing distance and viewing angle have greatly changed, the original disparities mapping into the appropriate ranges in the new display environment is needed to maintain the appropriate 3D depth comfortable zone [23][24][25].…”

“…Since the viewing distance and viewing angle have greatly changed, the original disparities mapping into the appropriate ranges in the new display environment is needed to maintain the appropriate 3D depth comfortable zone [23][24][25]. In [23], the global-shift based disparity transform is proposed to process the 3D content conversion. The basic viewing geometry change from cinema to 3DTV is shown in Fig.…”

“…Generally, the global-shift based disparity transform is considered as one solution for cinema-to-3DTV content conversion. Specifically, the absolute global shift based depth correction can be computed [23] as…”
