Abstract
Digitized pictures are subjected to shape-adaptive transformation coding and a inverse, shaped transformation coding. The signal energy of the coding information of the pixels to be transformed is, in the local area, approximately identical to the signal energy of the coding information of the transformed pixels in the frequency domain.
