Abstract

The-state-of-art High Efficiency Video Coding(HEVC) is designed towards the natural picture. Screen Content picture contains many similarities in one picture which can be used to improve the intra picture compression ratio. We propose sample rearrangement and template matching method by exploiting the similarities in the screen content picture. The 21 pixels template and the high efficiency multiple hash table are designed. Experiment results show that our proposal method can improve the lossless compression ratio by up to 4.23 times than HEVC Range Extensions.
