Methods and apparatus for attaching compressed look-up table (LUT) representations of N to M-dimensional transforms to image data and for processing image data utilizing the attached compressed LUTs

摘要

Each member of a set of transform representative data structures (such as look-up tables (LUTs), each representing an N TO M-dimensional transform), is stored in compressed form in a storage device included in, or which is otherwise accessible to, an image processing device or system. Each stored transform representative data structure may then, according to one embodiment of the invention, be selectively attached to image data being processed by the image processing device or system. According to a further aspect of the invention, image data, having compressed transform representative data attached thereto, may be processed utilizing methods and apparatus operative to detach, decompress and apply the transform represented by the decompressed transform representative data, to a decompressed version of the image data. The result of the aforementioned process is for image data to be transformed according to a transform specified by information previously attached to the image data.
