Abstract
According to various embodiments, a light-field image may be compressed and/or decompressed to facilitate storage, transmission, or other functions related to the light-field image. A light-field image may be captured by a light-field image capture device having an image sensor and a microlens array. The light-field image may be received in a data store. A processor may generate a first refocus image pool with a plurality of refocus images based on the light-field image. The processor may further use the first refocus image pool to compress the light-field image to generate a bitstream, smaller than the light-field image, which is representative of the light-field image. The processor or a different processor may also be used to generate a second refocus image pool with a second plurality of images based on the bitstream. The second refocus image pool may be used to decompress the bitstream to generate a reconstructed light-field image.
