1. An apparatus for block-based predictive decoding of a picture, the apparatus comprising:
a processor configured to:
predict a predetermined block of the picture to acquire a first version of a predicted filling of the predetermined block;
decode a residual signal from a data stream;
correct a prediction signal for a neighborhood of the predetermined block using the residual signal to obtain a reconstructed version of the neighborhood of the predetermined block;
spectrally decompose a region composed of the first version of the predicted filling of the predetermined block and the reconstructed version of the neighborhood of the predetermined block so as to acquire a first spectrum of the region;
perform noise reduction on the first spectrum to acquire a second spectrum;
acquire a modified version of the region including a second version of the predicted filling of the predetermined block by subjecting the second spectrum to spectral composition; and
correct the second version of the predicted filling using the residual signal to obtain reconstructed version of the predetermined block.
