A remarkable compress performance was achieved in the surveillance video coding when high-quality reconstructed background frames were referenced in long-term. However, the high-quality reconstructed background frames lead to bursting bit-rate peaks in the video transmission, which may cause obvious communication delay or buffer overflow. In order to address this problem, the paper proposes a quality-progressive...
To reduce the surveillance video coding cost, it is intuitive to encode surveillance videos by dealing with the foreground objects and the background separately. One widely used method following this strategy is Region-of-Interest (ROI) based coding. To achieve significant improvement for the coding efficiency of ROI based methods, this paper presents a surveillance video coding method with High Efficiency...
To save the storage and transmission cost, it is applicable now to develop fast and efficient methods to transcode the perennial surveillance videos to HEVC ones, since HEVC has doubled the compression ratio. Considering the long-time static background characteristic of surveillance videos, this paper presents a coding unit (CU) classification based AVC-to-HEVC transcoding method with background modeling...
