A kind of evaluation methodology of smoothness without reference video based on ORB operator

The present invention relates to the evaluation methodology of a kind of smoothness without reference video based on ORB operator, comprise the following steps: take video continuous n two field picture, extract the ORB characteristic point in n two field picture；ORB characteristic point in the most adjacent two two field pictures is mated；The ORB characteristic point of the most adjacent two two field picture error hiding is screened and rejected；Generate the affine transformation matrix between adjacent two two field pictures, the homography matrix between the most adjacent two two field pictures according to motion affine Transform Model, homography matrix A is carried out progressive alternate and solves；Calculating the kinematic parameter between the most adjacent two two field pictures, described kinematic parameter includes translation and the anglec of rotation of image；Generate video sequence translational motion track and rotary motion track；Utilize Gaussian filter to be filtered translational motion track and rotary motion track processing, obtain filtered translation track, rotary motion track；Calculate translation shake number and rotation shake number, and calculated level smoothness value and rotate smoothness value and judge video smoothing degree.
