Abstract :
This paper proposes an object-based approach to plenoptic videos, where the plenoptic video sequences are segmented into image-based rendering (IBR) objects each with its image sequence, depth map and other relevant information such as shape information. This allows desirable functionalities such as scalability of contents, error resilience, and interactivity with individual IBR objects to be supported. A portable capturing system consisting of two linear camera arrays, each hosting 6 JVC video cameras, was developed to verify the proposed approach. Rendering and compression results of real-world scenes demonstrate the usefulness and good quality of the proposed approach.
