Abstract

RAW images and/or light field images may be compressed through the use of specialized techniques. The color depth of a light field image may be reduced through the use of a bit reduction algorithm such as a K-means algorithm. The image may then be retiled to group pixels of similar intensities and/or colors. The retiled image may be padded with extra pixel rows and/or pixel columns as needed, and compressed through the use of an image compression algorithm. The compressed image may be assembled with metadata pertinent to the manner in which compression was done to form a compressed image file. The compressed image file may be decompressed by following the compression method in reverse.
