| Popis: | The High Efficiency Video Coding (HEVC) efficiently reduces the size of the multimedia contents, but at the cost of high computation complexity. In order to make it work for the real time applications, a study is conducted in this article to speed up the intra mode decision of HEVC. Firstly, a novel early termination mechanism is proposed that is based on the duration problem. This model is designed such that it requires the least amount of computation and dynamically adjusts to the current best option. Secondly, a dynamic threshold is proposed that outperformed majority of the thresholds in-terms of computation and adjustment with-respect-to the current best option. Experimental results proved that when the proposed methods are incorporated in HEVC, they reduced the encoding time by 34.1% on average, with a minor bit-rate (BD-BR) increase of 1.4% on average. |
