Sway perception amount estimation device and movement perception amount estimation program

摘要

PROBLEM TO BE SOLVED: To accurately estimate a trembling amount which a viewer who views a trembling video recognizes, namely a trembling recognition amount.SOLUTION: A trembling recognition amount estimation device 1 comprises: a movement vector for every area detection part 10 for detecting a movement vector; a movement area determination part 30 for determining presence/absence of movement; a movement area number application part 40 for applying a movement area number; a rotation center rotation angle calculation part 50 for acquiring a rotation center and a rotation angle in whole screen; a rotation vector calculation part 60 for acquiring a rotation vector; a rotation residual vector calculation part 70 for acquiring a rotation residual vector; a space frequency energy calculation part 100 for acquiring a corrected space frequency energy; a correlation value between movement areas calculation part 110 for acquiring a correlation value between movement areas; a correlation value between a boundary and an inner part of a movement area calculation part 120 for acquiring a correlation value between a boundary and an inner part of a movement area; and a total trembling energy calculation part 130 for calculating a total trembling energy.SELECTED DRAWING: Figure 2
