Abstract

Embodiments are provided for batch compression of photos. In some embodiments, first and second images are selected, each image comprising a plurality of individual blocks and each individual block is defined by at least one matrix whose values are indicative of pixel data within the individual block. For each individual block of the second image, comparing a chosen individual block of the second image to each individual block within at least one region of the first image. The comparing including calculating a difference block between the chosen block of the second image and a chosen block within the at least one region of the first image, the difference block comprising a difference between corresponding matrix values of the two blocks being compared, and calculating a sum for the calculated difference block as a similarity metric for the two blocks being compared. A similar difference block is provided from the calculated difference blocks for inclusion in a difference representation based on the corresponding sum, the similar difference block operable with the chosen block within the at least one region of the first image to reconstruct the chosen individual block of the second image, and compressing the difference representation and the first image, where the difference representation is operable with the first image to reconstruct the second image, and transmitting the compressed information.
