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.
Claims17
A gaze estimation system, comprising:
- a memory that stores a set of instructions;
- and
- at least one processor configured to execute the set of instructions to:
- estimate a plurality of gazes of a person included in a face image, by using a plurality of estimators, based on a degree that a range of the gaze indicated by first condition information overlaps a range of the gaze indicated by second condition information, the first and second condition information including the range of the gaze to be estimated;
- determine a gaze of the person, based on the first condition information including a condition relating to capture of the face image, a plurality of pieces of the second condition information each including the condition associated with one estimator of the plurality of estimators, and the plurality of gazes estimated;
- and
- execute weighted calculation conforming to a weight determined for each of the 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 a degree of overlapping of the range indicated by the first condition information, and the second condition information.
A gaze estimation method, comprising:
- by an information processing device:
- estimating a plurality of gazes of a person included in a face image, by using a plurality of estimators, based on a degree that a range of the gaze indicated by first condition information overlaps a range of the gaze indicated by second condition information, the first and second condition information including the range of the gaze to be estimated;
- determining a gaze of the person, based on the first condition information including a condition relating to capture of the face image, a plurality of pieces of the second condition information each including the condition associated with one estimator of the plurality of estimators, and the plurality of gazes estimated;
- and
- execute weighted calculation conforming to a weight determined for each of the 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 a degree of overlapping of the range indicated by the first condition information, and the second condition information.
A non-transitory computer-readable storage medium storing a program causing a computer to execute:
- processing of estimating a plurality of gazes of a person included in a face image, by using a plurality of estimators, based on a degree that a range of the gaze indicated by first condition information overlaps a range of the gaze indicated by second condition information, the first and second condition information including the range of the gaze to be estimated;
- processing of determining a gaze of the person, based on the first condition information including a condition relating to capture of the face image, a plurality of pieces of the second information each including the condition associated with one estimator of the plurality of estimators, and the plurality of gazes estimated;
- and
- execute weighted calculation conforming to a weight determined for each of the 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 a degree of overlapping of the range indicated by the first condition information, and the second condition information.
