Embodiment Construction
[0037] The present invention will be further described in detail with reference to the accompanying drawings and embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0038] refer to figure 1 , the implementation steps of the present invention are as follows:
[0039] Step 1: Classify the motion intensity of the video sequence.
[0040] 1a) For the current coding unit CU 0 build motion vector collection {mv 1 ,mv 2 ,mv 3 ,mv 4 ,mv 5},
[0041] where mv i is the current coding unit CU 0 Surrounding Coding Unit CU i The motion vector, mv i =(x i ,y i ), i=1,...,5,x i and y i Respectively, the abscissa and ordinate of the motion vector; CU 0 The surrounding coding unit set includes its left adjacent coding unit CU 1 , upper adjacent coding un...
