Abstract(s)

The recently introduced quadtree coding structures used in HEVC increase compression efficiency in comparison to previous standards at the cost of higher computational complexity levels. This paper proposes an evolution of a complexity control method for HEVC encoders based on the dynamic adjustment of these structures' maximum depth. The new method improves the previous solution by adopting a new control strategy and compensating the motion effect on a maximum tree depth map which is central to the complexity control strategy. The proposed method is capable of performing a more accurate complexity control than our previous strategy while still reducing compression efficiency losses in terms of image quality and bit rate.
