EVALUATION APPARATUS AND METHOD

摘要

An evaluation apparatus includes: a memory; and a processor coupled to the memory and configured to calculate a first feature by calculating a first-order difference for a first image, calculate a second feature by calculating a second-order difference for the first image, calculate a third feature by calculating a first-order difference for a second image, calculate a fourth feature by calculating a second-order difference for the second image, and evaluate deterioration of the second image with respect to the first image according to a first simultaneous distribution that represents a first relationship between the first feature and the second feature and to a second simultaneous distribution that represents a second relationship between the third feature and the fourth feature.
