Embodiment Construction
[0052] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
[0053] A HEVC rate-distortion optimization algorithm based on just observable perceptual quality decision criteria, such as figure 1 As shown, including the following steps:
[0054] Step 1. Before making mode decision on the encoding end of the high-efficiency video codec, analyze the motion mode and static texture characteristics of each macroblock in each frame to obtain the current macroblock's perceptual quality type, and according to different motion states Obtain a significant area of the image.
[0055] In this step, for each coding unit CU of each frame, and each of its divided blocks, first establish a complete set of state attribute descriptors (Representing the state of the k-th macroblock in a frame at time t), as follows:
[0056] s k t = Normal state ( NS ) if MV k t ≠ 0 , R k t ...
