Abstract
A method for compressing images includes identifying a set of image blocks from a plurality of digital images. For each image block from the set, image features of the image block are extracted. The set of image blocks is sorted into an ordered sequence of image blocks based on an average image feature difference between sequentially sorted image blocks. The set of image blocks is compressed into compressed image data based on inter block correlations between image blocks in the ordered sequence.
