  • Image Bit-Depth Expansion Method Based On Sparse Representations 

    Záviška, Pavel (Vysoké učení technické v Brně, Fakulta elektrotechniky a komunikačních technologií, 2018)
    In this paper, a method for restoration of low bit-depth images based on sparse representations is presented. Proposed method is independent on the transform used, however for the purposes of experiments, Discrete Cosine ...
