View-spatial–temporal post-refinement for view synthesis in 3D video systems

作者:

Highlights:

• Propose a post-refinement method to improve the rendering quality of synthesized image.

• Propose hole filling and boundary artifacts removal technologies.

• View-spatial–temporal correlations of mutiview video are efficiently used to improve the rendering quality.

• A good trade-off between complexity and rendering quality is achieved in reference frame selection.

• Both subjective and objective qualities of rendered images are significantly improved.
