Method for the reconstruction of compressed digital image data

摘要

The invention relates to a method for the reconstruction of digital image data which has been lossy-compressed by transform coding and quantization, comprising the steps of
a) Inputting JPEG-compressed digital image data (J comp );
b) Iteratively performing updates of an extended image model, thereby reducing the total generalized variation functional constrained to all images matching the transform coded, quantized data;
c) Outputting a decompressed digital image (u).
