Compression of light field images

A method for processing a compressed image derived from a raw image projected from light field data acquired through a microlens array, the method comprising:

• retrieving a compressed image derived from a raw image projected from light field data, wherein the compressed image comprises a plurality of retiled pixel clusters;
• and
• at a processor, retiling the compressed image to generate a reverted image comprising a plurality of reverted pixel clusters, each of which comprises a pixel from each of the retiled pixel clusters;
• wherein each of the reverted pixel clusters encodes a portion of the light field data corresponding to a microlens of the microlens array.

A computer program product for compressing an image projected from light field data acquired through a microlens array, the computer program product comprising:

• a non-transitory storage medium;
• and
• computer program code, encoded on the medium, configured to cause at least one processor to perform the steps of:
• retrieving an image projected from light field data, wherein the image comprises a plurality of pixel clusters, each of which encodes a portion of the light field data corresponding to a microlens of the microlens array;
• retiling the image to generate a retiled image comprising a plurality of retiled pixel clusters, each of which comprises a pixel from each of the pixel clusters;
• and
• applying an image compression algorithm to the retiled image to generate a compressed image.

A system for compressing an image projected from light field data acquired through a microlens array, the system comprising:

• a storage device, configured to store an image;
• and
• a processor, communicatively coupled to the storage device, configured to:
• retrieve an image from the storage device, the image being projected from light field data, wherein the image comprises a plurality of pixel clusters, each of which encodes a portion of the light field data corresponding to a microlens of the microlens array;
• retile the image to generate a retiled image comprising a plurality of retiled pixel clusters, each of which comprises a pixel from each of the pixel clusters;
• and
• apply an image compression algorithm to the retiled image to generate a compressed image.
