  • Patent number: 11412233
    Abstract: Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, scene metadata and input light field images associated with a scene are received. A first encoding operation is performed on the scene metadata and input light field images to generate reference images, reference disparity information, and an order of reference views. A second encoding operation is performed based on the reference images and reference disparity information to output light field encoded data. The light field encoded data includes the encoded reference images, the encoded reference disparity information, and the order of reference views. The light field encoded data is transmitted.

  • Publication number: 20180352209
    Abstract: Methods and systems for compression of light field images using Multiple Reference Depth Image-Based Rendering techniques (MR-DIBR) are disclosed. The methods and systems enhance light field image quality of compressed light field images using reference depth (or disparity) and color maps to enable hole filling and crack filling in compressed light field image data sets.
