FIELD: information technology.
SUBSTANCE: apparatus for generating multiple candidate coding trees for use during encoding comprises: a computer configured for receiving and processing images and/or video frames; and a program executable on said computer for generating a non-directional coding tree using octave-band partitioning; generating horizontal and vertical coding trees in response to scaling frequency components in a horizontal or vertical direction, and octave-band partitioning to create multiple candidate coding trees adapted for horizontal and vertical directions.
EFFECT: higher coding efficiency.
