Abstract
Described are a method, apparatus and computer program product are provided for block modulating video and image compression. Different masks may be imposed on different blocks of an image and then the blocks summed to one block. In some embodiments, an encoder complexity of the encoder may be O(1). A method can be carried out that includes dividing an input image into a plurality of blocks; assigning different masks to each respective image block of the plurality of image blocks, the different masks having a size equal to that of each respective image block of the plurality of image blocks; modulating each respective image block of the plurality of blocks the assigned different masks to generate a plurality of modulated image blocks; summing the modulated plurality of blocks to at least one summed block; and quantizing the at least one summed block.
