SALIENCY DEGREE ESTIMATION METHOD, SALIENCY DEGREE ESTIMATION DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a saliency degree estimation method capable of estimating the saliency degree of objective sound based on unpredictability of a time series pattern.SOLUTION: A saliency degree estimation method estimates the saliency degree of sound in part of the time section of an input signal and includes: a similar partial section detection step for detecting one or more similar partial sections that is a partial section similar to a reference signal from within a storage interval; a prediction distribution generation step for generating one or more prediction distributions that is a distribution based on the feature quantity of an input signal corresponding to a predetermined time section just after the detected similar partial section; and a saliency degree estimation step for estimating the saliency degree of an input signal corresponding to a prediction interval based on the generated prediction distribution and an estimation object signal.SELECTED DRAWING: Figure 1
