Abstract:
A method for vector quantization and for inverse vector quantization of a digitized image, comprising the steps of:grouping at least a part of image points of the digitized image into at least one image region to be quantized and into at least one image region that is not to be quantized; imaging image information of the image region to be quantized onto an entry in a code book with which the image information of the image region to be quantized is approximately described; allocating the entry of the code book to the image region to be quantized; imaging the entry onto an approximated item of image information contained in the code book; reconstructing the quantized image region from the approximated image information; and reconstructing the region of the image that was not quantized by at least one of interpolation and extrapolation of image information of the quantized image region.
