Abstract: The production of curved displays has substantially increased in the past years. This new type of displays can enhance the feeling of immersion by surrounding the viewers with content. In this paper, we propose a content-aware and depth-aware video deformation method for projection of rectangular content on curved displays. Novel deformation and grid-based mapping methods are proposed to prevent over-preservation of foreground content for static and dynamic content and to enforce temporal coherence. The objective evaluation of the results shows that our approach efficiently and consistently preserves both static and dynamic content. A thorough subjective evaluation is also performed using a real-world curved screen as well as a virtual reality setup, showcasing our method against existing methods. Experimental results indicate that our method systematically outperforms the existing state-of-the-art, providing minimal content distortion and high temporal coherence between consecutive frames.
