Due to geometry issues related to depth rendering, adaptation from a cinema environment to the home environment is far from being an automatic, straightforward process for 3-D content production. Automated content-based postproduction or postprocessing tools to help adapt 3-D content to television are expected to be developed. Three-dimensional visual attention models can be employed to provide the area of interest and convergence plane to drive the content repurposing of stereoscopic content. In addition, the adaptation of the scene depth can be used to improve visual comfort. To reduce both visual discomfort and fatigue, the convergence plane is usually continuously set to the main area of interest, as the latter moves across different depth levels. A way to reduce eye strain is to modify the convergence plane of the main area of interest to place it on the display plane, i.e., by adapting the content disparity. Such visual-attentionbased adaptive rendering of 3-D stereoscopic video has been proposed using a 2-D visual attention model [91].
