Abstract:
Existing Light Field (LF) refocusing techniques refocus to all the pixels of a certain depth plane. However, in reality, the human eye focuses only on the object of interest while everything else is in depth-wise out of focus. In this paper, we propose a LF refocusing technique that is consistent with human visual perception. To this end, we perform instance segmentation on LF content and bring the whole object of interest in-focus rather than only the parts of the object that are in the same depth plane or all the objects that are on the same depth plane as the object of interest. Experimental results show that the proposed method is more consistent with the human visual perception than existing methods, yielding significantly improved visual quality results.
