Expression determination device, expression determination method, and recording medium
First Claim
Patent Images
1. An expression determination device comprising a processor:
- wherein the processor is configured to;
acquire image data;
detect a face of a person from the acquired image data;
estimate an angle of the detected face;
acquire a single expression score indicating a degree of expression of an expression worn by the face; and
determine the expression worn by the face by calculating a single corrected score that is obtained by correcting the acquired single expression score based on the estimated angle of the face.

Abstract
A determination result is easily obtained even in expression determination on a face image that is not a front view. A Robot includes a camera, a face detector, a face angle estimator, and an expression determiner. The camera acquires image data. The face detector detects a face of a person from the image data acquired by the camera. The face angle estimator estimates an angle of the face detected by the face detector. The expression determiner determines an expression of the face based on the angle estimated by the face angle estimator.

15. An expression determination method, comprising:
-
acquiring image data; detecting a face of a person from the acquired image data; estimating an angle of the detected face; and acquiring a single expression score indicating a degree of expression of an expression worn by the face, and determining the expression worn by the face by calculating a single corrected score that is obtained by correcting the acquired single expression score based on the estimated angle of the face.

16. A non-transitory computer-readable recording medium storing a program, the program causing a computer to:
-
acquire image data; detect a face of a person from the acquired image data; estimate an angle of the detected face; and acquire a single expression score indicating a degree of expression of an expression worn by the face, and determine the expression worn by the face by calculating a single corrected score obtained by correcting the acquired single expression score based on the estimated angle of the face.
