The Use of a Dense Disparity Map to Enhance Quality of Experience in Stereoscopic 3D Content

What stereoscopic 3D content brings to the viewer is essentially a binocular cue to better understand the depth of a scene. A disparity map associated to the stereoscopic content is a key data to ensure that the 3D effect will be well accepted by the user. Limitation of the human vision system in term of binocular cue acceptance will be presented. It will explain when specific video processing can improve the quality of experience. Several uses cases either in post-production or on the end-user side will be presented. All of them will use the dense disparity map as additional input data. Means to generate this disparity map will be introduced. Then technical details of disparity-based algorithms will be presented as well as their positioning in the global 3D workflow. Some standardization challenges will also be addressed
