Abstract
A determination method includes acquiring a plurality of images which are captured at different times by a camera; and determining, when each of the plurality of images includes a first image region of a face of a person and a second image region which is located outside the first image region and has a shape which satisfies a predetermined condition, whether the face of the person is a display object based on a state of change in a positional relationship between the first image region and the second image region between the plurality of images.
Claims10
A determination method comprising:
- acquiring a plurality of images which are captured at different times by a camera;
- detecting a first image region of a face of a person in each of the plurality of images;
- generating, from each of the plurality of images, a respective rectangular image by rotationally transforming the image so that a line segment coupling left and right eyes of the person represented in the first image region is parallel to one end of the rectangular image;
- detecting a first linear image region and a second linear image region in each of the plurality of rectangular images, wherein the first linear image region is detected by a detection process starting from a pixel column parallel to the line segment, and the second linear image region is detected by a detection process starting from a pixel column perpendicular to the line segment;
- and
- determining whether the face of the person is a display object based on a state of change in a positional relationship between the first image region and the first linear image region and a state of change in a positional relationship between the first image region and the second linear image region, between the plurality of images.
