Palette mode is the new coding tool that has been adopted in the Screen Content Coding Extensions of High Efficiency Video Coding (HEVC SCC). Palette mode can represent colour clusters for screen content efficiently and can be summarized into two parts: palette coding tools and colour index map coding tools. This paper proposes two techniques to improve colour index map coding: transition copy and...
Palette mode, as a new coding tool, is adopted in the Screen Content Coding Extensions of High Efficiency Video Coding (HEVC SCC) that is being defined by the Joint Collaborative Team on Video Coding (JCT-VC). In the palette mode, pixels in a coding unit (CU) are represented by selected representative colours according to the characteristics of screen contents in which pixel values usually concentrate...
As the state-of-the-art video coding standard, High Efficiency Video Coding (HEVC) has been finalized in January 2013. To support the coding of multiple views and associated depth data, the development of the HEVC extension for 3D video coding is also about to be finalized. New coding unit (CU) level coding tools are added to the HEVC design to improve the compression capabilities for both video views...
This paper presents a novel inter-view motion prediction technique used in 3D-HEVC which provides efficient compression for motion vectors. The 3D extension of HEVC (High Efficiency Video Coding) namely 3D-HEVC is under development in JCT-3V for coding multi-view video and depth data. Inter-view motion prediction takes benefit of the inter-view correlation between views by inferring the motion information...
High Efficiency Video Coding (HEVC) is an emerging international video coding standard developed by the Joint Collaborative Team on Video Coding (JCT-VC). Compared to H.264/AVC, HEVC has achieved substantial compression performance improvement. During the HEVC standardization, we proposed several motion vector coding techniques, which were crosschecked by other experts and then adopted into the standard...
