A fast algorithm of intra prediction modes pruning for HEVC based on decision trees and a new three-step search
Abstract
The High Efficiency Video Coding (HEVC) standard is a new generation video coding scheme, succeeding to H.264/AVC. HEVC requires only 50 % bitrate of H.264/AVC at the same perceptual quality by adopting new coding tools and more flexible block structures. HEVC specifies 35 different intra prediction directions that can be associated to different block sizes. Each possible combination needs to be tested within the Rate Distortion (RD) process to …
