Objective image quality evaluation device, objective image quality evaluation method and program

摘要

PROBLEM TO BE SOLVED: To estimate objective image quality without using an original image and a decoded image and a prediction residual signal.SOLUTION: An objective image quality evaluation device 1 includes a parameter analysis unit 10, a complexity calculation unit 20, and an image quality deterioration feature amount integration unit 50. The parameter analysis unit 10 obtains block depth information SIG2, corresponding to the number of division times when dividing a coded unit block recursively by quadtree structure, from a bit stream SIG1. The complexity calculation unit 20 obtains complexity feature amount SIG8, related to the complexity of a frame, on the basis of the block depth obtained by the parameter analysis unit 10. The image quality deterioration feature amount integration unit 50 performs objective image quality evaluation, on the basis of the complexity feature amount obtained by the complexity calculation unit 20.SELECTED DRAWING: Figure 1
