Extending the FOV from disparity and color consistencies in multiview light fields

Light field, which is captured by a plenoptic camera, is always limited in its narrow field of view (FOV) by the physical size of the aperture. To break through the restriction, we propose to extend the FOV using multiview light fields. A series of light fields are acquired by translating the camera at isometric spatial positions. In contrast to previous methods, our algorithm is the first that achieves light field registration and rendering based on epipolar plane image (EPI) properties, including disparity and color consistencies. Furthermore, the aliasing caused by the under-sampling in the angular space is eliminated by synthesizing novel views in the EPI space. Experimental results on the real scene data have demonstrated the effectiveness of our algorithm.
