Abstract
The purpose of the present invention is to improve the accuracy of line-of-sight estimation based on an image. A line-of-sight estimation device 100 comprises: an estimation unit 110 which estimates lines of sight from a face included in a face image, using a plurality of estimators; and a determination unit 120 which determines a line of sight for the face on the basis of first condition information including conditions relating to the capture of the face image, and a plurality of sets of second condition information, each including conditions associated with one of the plurality of estimators, and on the basis of a plurality of estimated lines of sight.
Claims8
A gaze estimation device, comprising:
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to perform:
- estimating a gaze of a face included in a face image with a plurality of estimators;
- and
- determining a gaze of the face, based on first condition information including a condition relating to capture of the face image, a plurality of pieces of second condition information each including the condition associated with one estimator the plurality of estimators, and the estimated plurality of gazes, wherein the condition includes a range of the gaze to be estimated;
- and
- executing weighted calculation conforming to a weight determined for each of a plurality of gazes estimated by the plurality of estimators, and determined depending on the second condition information associated with the one estimator and the first condition information;
- wherein the weight is determined based on an overlap ratio at which ranges of gazes overlap.
A gaze estimation method, comprising:
- estimating a gaze of a face included in a face image with a plurality of estimators;
- and
- determining a gaze of the face, based on first condition information including a condition relating to capture of the face image, a plurality of pieces of second condition information each including the condition associated with one estimator the plurality of estimators, and the estimated plurality of gazes, wherein the condition includes a range of the gaze to be estimated;
- and
- executing weighted calculation conforming to a weight determined for each of a plurality of gazes estimated by the plurality of estimators, and determined depending on the second condition information associated with the one estimator and the first condition information;
- wherein the weight is determined based on an overlap ratio at which ranges of gazes overlap.
A non-transitory computer-readable program recording medium recording a program which causes a computer to execute:
- processing of estimating a gaze of a face included in a face image with a plurality of estimators;
- and
- processing of determining a gaze of the face, based on first condition information including a condition relating to capture of the face image, a plurality of pieces of second condition information each including the condition associated with one estimator the plurality of estimators, and the estimated plurality of gazes, wherein the condition includes a range of the gaze to be estimated;
- and
- processing of executing weighted calculation conforming to a weight determined for each of a plurality of gazes estimated by the plurality of estimators, and determined depending on the second condition information associated with the one estimator and the first condition informations;
- wherein the weight is determined based on an overlap ratio at which ranges of gazes overlap.
