Abstract: Disclosed herein is a method, in particular for interpolating and smoothening the gamut boundary of an image processing device. Color data are received. An initial surface corresponding to the color data in a color space is created and divided into first patches. A first one of the first patches is divided into second patches based on a topology of a second one of the first patches. Further disclosed are a corresponding machine-readable medium and a corresponding system comprising a storage device and a computing device.

Abstract: Methods of image compression are described. A stream of color image data is filtered with a prediction routine using a pixel neighborhood. The filtered stream of color image data is sorted with a block sorting routing. A version of the color image data is compressed based on the sorted and filtered stream of color image data.
