Abstract
Methods and systems are provided for image processing. A plurality of correlation parameters representing degrees of correlation between two or more images of a plurality of images may be determined. An optimized correlation dependency graph may be generated according to the plurality of correlation parameters. The plurality of images may then be delta encoded according to the optimized correlation dependency graph. For example, the optimized correlation dependency graph may be used for performing a predetermined correlation encoding operation. The plurality of correlation parameters may be determined, for example, in accordance with one or more predetermined correlation metrics associated with the predetermined correlation encoding operation.
