COMPUTER PROGRAM FOR BOTTOM-UP PRUNING METHOD APPLIING TO HIGH EFFICIENCY VIDEO CODING AND APPARATUS THEREFOR

摘要

The present invention provides a computer program for a bottom-up pruning scheme applied to a high efficiency video coding (HEVC) intra-prediction, which comprises the steps of: (a) determining whether partition blocks with a second depth level constituting lower nodes of partition blocks with a first depth level according to a hierarchical structure of a coding tree unit (CTU) correspond to a leaf node or a tree node; and (b) determining whether the intra-prediction for the partition blocks with the first depth are performed based on information on a difference between a leaf node average value, which is an average value of rate distortion costs of the partition blocks with the second depth level determined as the leaf node, and a tree node average value, which is an average value of rate distortion costs of the partition blocks with the second depth level determined as the tree node.
