Abstract
A determination method for a computer to execute a process includes acquiring a captured image that is captured by a camera and includes an image area of a person; specifying an image area other than the image area of the person from the acquired captured image; and determining whether the captured image is obtained by capturing a display object of the person according to a distribution of motions of a plurality of positions included in the specified image area.
Claims12
A determination method for a computer to execute a process comprising:
- acquiring a captured image that is captured by a camera and includes an image area of a person;
- specifying an image area other than the image area of the person from the acquired captured image;
- and
- determining whether the captured image is obtained by capturing a display object of the person according to a distribution of motions of a plurality of positions included in the specified image area, wherein
- the image area other than the image area of the person includes a peripheral area that is an annular area that has an edge of the captured image as an outer periphery, and a background area that is an area other than the image area of the person among areas surrounded by an inner periphery of the peripheral area, and
- the determining includes determining according to a distribution of motions of a first position included in the background area and a distribution of motions of a second position included in the peripheral area.
A non-transitory computer-readable storage medium storing a determination program that causes at least one computer to execute a process, the process comprising:
- acquiring a captured image that is captured by a camera and includes an image area of a person;
- specifying an image area other than the image area of the person from the acquired captured image;
- and
- determining whether the captured image is obtained by capturing a display object of the person according to a distribution of motions of a plurality of positions included in the specified image area, wherein
- the image area other than the image area of the person includes a peripheral area that is an annular area that has an edge of the captured image as an outer periphery, and a background area that is an area other than the image area of the person among areas surrounded by an inner periphery of the peripheral area, and
- the determining includes determining according to a distribution of motions of a first position included in the background area and a distribution of motions of a second position included in the peripheral area.
An information processing apparatus comprising:
- one or more memories;
- and
- one or more processors coupled to the one or more memories and the one or more processors configured to:
- acquire a captured image that is captured by a camera and includes an image area of a person,
- specify an image area other than the image area of the person from the acquired captured image, and
- determine whether the captured image is obtained by capturing a display object of the person according to a distribution of motions of a plurality of positions included in the specified image area, wherein
- the image area other than the image area of the person includes a peripheral area that is an annular area that has an edge of the captured image as an outer periphery, and a background area that is an area other than the image area of the person among areas surrounded by an inner periphery of the peripheral area, and
- the determining includes determining according to a distribution of motions of a first position included in the background area and a distribution of motions of a second position included in the peripheral area.
