METHOD AND ARRANGEMENT FOR VECTOR QUANTIZATION AND FOR REVERSE VECTOR QUANTIZATION OF A DIGITIZED IMAGE

摘要

In a vector quantization of a digitized image, image regions (QB) to be quantized are selected smaller than, for example, image blocks (BB) of an image (B). In the reconstruction, image points (NBP) that are not located in an image region (QB) to be quantized are interpolated and/or extrapolated.
