Stereo-video - Video-plus-depth - Impaired videos - Test sequences

Using the streams from the stereo-video database a database of video plus depth was created. Depth was estimated using Hybrid Recursive Matching (HRM) previously developed at FHG-HHI for the left view of each stereo pair. Then, the corresponding right view was rendered from the left view and the estimated depth. For quality assessment the visual impression was evaluated inspecting synthesized right views and the stereo impression on small displays for mobile applications. The algorithm used for depth estimation is described in a technical report on generation of stereo video data base, which is available in the publications section or our website.

Artefacts are visible in the synthesized right views. This is an inherent problem of video plus depth approach for stereo. Depth estimation can never be perfect and can only be solved up to a residual error probability. The task is to minimize errors and to ensure that they have a minimum effect on the visual quality. Due to masking effects with the original left view, artefacts are almost not noticeable when watching stereo on a small display, which was found by visual inspection.

The FhG-HHI data can be downloaded from an FTP server (see the details on the right). Please, contact Gerhard Tech for more information on other downloadable material.
