1. An apparatus for block-based predictive decoding of a picture, comprising:

  • a prediction provider configured to predict a predetermined block of the picture to acquire a first version of a predicted filling of the predetermined block;

    a spectral decomposer configured to spectrally decompose a region composed of the first version of the predicted filling of the predetermined block and a reconstructed version of a neighborhood of the predetermined block so as to acquire a first spectrum of the region;

    a noise reducer configured to perform noise reduction on the first spectrum to acquire a second spectrum;

    a spectral composer configured to subject the second spectrum to spectral composition so as to acquire a modified version of the region including a second version of the predicted filling of the predetermined block;

    a reconstructor configured to decode a reconstructed version of the predetermined block from a data stream on the basis of the second version of the predicted filling.
