Abstract
A computer-implemented method of selecting a sequence of images of a user's eye for an eye tracking application wherein each image is captured when a stationary stimulus point is displayed to the user, the method comprising: for a plurality of different pairs of the images: comparing the pair of images with each other to determine an image-score that represents a degree of difference between the compared images; and calculating a sequence-score based on the image-scores for the plurality of pairs of images.
Claims20
A computer-implemented method of selecting a sequence of images of a user's eye for an eye tracking application wherein each image is captured when a stationary stimulus point is displayed to the user, the method comprising, for a plurality of different pairs of the images:
- comparing the pair of images with each other to determine an image-score that represents a degree of difference between the compared images;
- and
- calculating a sequence-score based on the image-scores for the plurality of pairs of images.
A processor configured to:
- receive a sequence of images of a user's eye for an eye tracking application;
- for a plurality of different pairs of the images:
- compare the pair of images with each other to determine an image-score that represents a degree of difference between the compared images;
- and
- calculate a sequence-score based on the image-scores for the plurality of pairs of images.
A non-transitory computer-readable storage medium storing instructions which, when executed by a cause the computer to carry out the steps of:
- selecting a sequence of images of a user's eye for an eye tracking application wherein each image is captured when a stationary stimulus point is displayed to the user,
- comparing a plurality of different pairs of the images with each other to determine an image-score that represents a degree of difference between the compared images;
- and
- calculating a sequence-score based on the image-scores for the plurality of pairs of images.
