Abstract
A machine may be configured to process an uncompressed image to obtain a set of intermediate images, which may be alternatively known as working images or temporary images. Such a set of intermediate images may be used as input for an image compression algorithm that, when executed by the machine or other compression engine, outputs a compressed version of the uncompressed image. For example, a compression format called “PVRTC,” which may be used on certain portable devices, accepts a set of three intermediate images as input, specifically, one full resolution, low precision version of the original uncompressed image, plus two low resolution, low frequency color versions of the original uncompressed image. A set of intermediate images for such a compression format may be generated by the machine from the original uncompressed image.
