| Popis: |
In this paper, we propose a fast rough mode decision method based on edge detection for intra coding in HEVC. It performs edge detection using Sobel operator and estimates the angular direction using gradient values. Histogram mapping is used to reduce the number of prediction modes for full rate-distortion optimization (RDO). The proposed method can achieve processing speed improvement through RDO computation reduction. Simulation results shows that encoding time is reduced significantly compared to HM-13.0 with acceptable BD-PSNR and BD-rate. |
