Abstract
A computer-implemented method includes dividing an image into one or more image channels for image compression. The method also includes dividing one or more of the image channels into one or more blocks. At least one of the blocks includes floating point representations of pixel values included in the block. The method also includes converting the floating point representations of pixel values into integer representations such that the sign of each floating point representation is preserved. The method also includes storing the difference of adjacent integer representations as a compressed version of the image.
