Abstract
The present invention is directed to systems and methods for compressing image data without segregating the image data into scanned and non-scanned components, while at the same time, improving both the compression ratio and the perceptabilty of the decompressed image. Improved perceptibility is realized regardless of whether the image data includes scanned images, non-scanned images or any combination thereof. Further, improved perceptibility is realized regardless of whether the images are monochrome or color.
