    摘要： 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.

    摘要： Methods and systems for light field compression are disclosed. According to some embodiments, the method receives pre-processing information that includes subimages associated with a scene. The method performs a first compression operation on the pre-processing information to generate reference information. The method further performs a second compression operation on the reference information and residual information to output compressed information. The compressed information includes compressed reference information and compressed residual information.

    摘要： A compression method for high-resolution light field display is disclosed for applications in which computer memory constraints and latency are critical. The disclosed compression algorithm takes advantage of the 3D structure of a light field to compress the raw light field information with a fixed compression ratio and simple decoding instructions. The compressed high-resolution light field achieves a reduced bandwidth with acceptable quality, and is packed in a way that can be transmitted using common interfaces. In a preferred embodiment, the compression algorithm is used as a post-processing stage after light field information acquisition or after rendering. In a further preferred embodiment, the compression algorithm is incorporated into the acquisition or rendering procedure to reduce memory and rendering processing. These and further embodiments generate a compressed light field with all information required for direct display.

    摘要： Methods and systems for light field image encoding and decoding are disclosed. According to some embodiments, the method receives scene metadata and input light field images associated with a scene. The method further performs a first encoding operation on the scene metadata and the input light field images to generate reference views and reference disparity information. The method further performs a second encoding operation based on the reference views, the reference disparity information, and synthesized residuals to output encoded light field data, where the encoded light field data comprises encoded reference views, encoded reference disparity information, and encoded synthesized residuals. The method further randomly accesses and selects a group of reference views and corresponding disparity information from the encoded light field data based on one or more selected regions of interest. And the method transmits the selected group of reference views, the selected corresponding disparity information, and the encoded synthesized residuals.
