FIELD: information technology.
SUBSTANCE: invention relates to forward and inverse decorrelation transformation of digital video images in video compression and decompression systems. The method is realised owing to possibility of decorrelating digital video images of arbitrary dimensions and not only dimensions equal to whole-number powers of two, which provides a device for decorrelating digital video images using integral orthogonal decorrelation matrices in video image compression systems.
EFFECT: wider field of use.
