WitrynaThe minimum CU size, or the minimum quad tree depth, is also a parameter of the encoding system and can take the values of 8x8, 16x16, 32x32, or 64x64. Spatial intra-prediction is performed in HEVC for square-shaped blocks called PUs (from Prediction Unit). The PU has the same size as the CU, with two exceptions. Witryna3 paź 2024 · The more flexible CU sizes improve the encoding efficiency while cause much heavier computational complexity than High-Efficiency Video Coding (HEVC). In this paper, an efficient low-complexity CU partition method based on the texture characteristic is proposed to achieve a good trade-off between the coding efficiency … http://www.jdl.link/doc/2011/20161162094892152_2015-%20journal%20of%20real%20time%20image%20processing-fast%20algorithms%20and%20vlsi%20architecture%20design%20for%20hevc%20intra-mode%20decision.pdf optum bh claims
