Abstract
Described are various embodiments of systems, methods and devices for transmitting, over a digital network, a digital image data object defined by a plurality of image pixels, wherein embodiments comprise: a digital image compressor operable to compress the digital image data object by independently compressing distinct pixel groups defined amongst the plurality of image pixels into independently compressed pixel groups to be transmitted over the digital network, in which, for each of said compressed pixel groups, a comparison value indicative of a similarity between given pixel data of a given group pixel and reference pixel data of a corresponding reference pixel is computed to at least partially replace said given pixel data; and a digital image decompressor coupled thereto operable to receive each of said independently compressed pixel groups for independent decompression.
