Abstract

Claims (32)

1 . An information processing apparatus comprising:

at least one memory configured to store instructions; and

at least one processor configured to execute the instructions to:

acquire a person image including an eye area of a target person with eyes closed;

perform, by the at least one processor, edge extraction processing on the person image to generate an edge image;

extract, from the edge image, an edge enclosing at least a part of an eye of the target person included in the eye area, an edge of an upper eyelid of the target person and an edge of a lower eyelid of the target person, while the eye of the target person is closed;

determine, in response to simultaneously detecting the edge enclosing the at least the part of the eye of the target person and both the edge of upper eyelid and the edge of lower eyelid while the eye of the target person is closed, a determination of whether the target person impersonates another person; and

output the result indicating that the target person impersonates another person,

wherein the at least one processor is further configured to determine whether or not an accessory having an aperture enclosing the at least the part of the eye of the target person is in the person image, and if it is determined the person is wearing an accessory having an aperture enclosing the at least the part of the eye, the target person impersonates another person.

2 . The information processing apparatus according to claim 1 , wherein the at least one processor is further configured to execute the instructions to acquire the person image from a plurality of person images that are captured continuously in time, and

wherein the plurality of person images includes the eye area of the target person.

3 . The information processing apparatus according to claim 1 , wherein the edge enclosing at least the part of the eye of the target person is the edge of an aperture formed in the accessory worn by the target person.

4 . An information processing method comprising:

acquiring, by at least one processor, a person image including an eye area of a target person with eyes closed;

performing, by the at least one processor, edge extraction processing on the person image to generate an edge image;

extract, from the edge image, an edge enclosing at least a part of an eye of the target person included in the eye area, an edge of an upper eyelid of the target person and an edge of a lower eyelid of the target person, while the eye of the target person is closed;

determining, by the at least one processor, in response to simultaneously detecting the edge enclosing the at least the part of the eye of the target person and both the edge of upper eyelid and the edge of lower eyelid while the eye of the target person is closed, a determination of whether the target person impersonates another person; and

output the result indicating that the target person impersonates another person,

wherein information processing method further comprises determining, by the at least one processor, whether or not an accessory having an aperture enclosing the at least the part of the eye of the target person is in the person image, and if it is determined the person is wearing an accessory having an aperture enclosing the at least the part of the eye, the target person impersonates another person.

5 . The information processing method according to claim 4 , the information processing method further comprising:

acquiring the person image from a plurality of person images that are captured continuously in time,

wherein the plurality of person images includes the eye area of the target person.

6 . A non-transitory recording medium storing a computer program, which when executed, causes a computer to execute an information processing method comprising:

acquiring, by at least one processor, a person image including an eye area of a target person with eyes closed;

performing, by the at least one processor, edge extraction processing on the person image to generate an edge image;

extract, from the edge image, an edge enclosing at least a part of an eye of the target person included in the eye area, an edge of an upper eyelid of the target person and an edge of a lower eyelid of the target person, while the eye of the target person is closed;

determining, by the at least one processor, in response to simultaneously detecting the edge enclosing the at least the part of the eye of the target person and both the edge of upper eyelid and the edge of lower eyelid while the eye of the target person is closed, a determination of whether the target person impersonates another person; and

output the result indicating that the target person impersonates another person,

wherein information processing method further comprises determining, by the at least one processor, whether or not an accessory having an aperture enclosing the at least the part of the eye of the target person is in the person image, and if it is determined the person is wearing an accessory having an aperture enclosing the at least the part of the eye, the target person impersonates another person.

7 . The non-transitory recording medium according to claim 6 , the information processing method further comprising:

acquiring the person image from a plurality of person images that are captured continuously in time,

wherein the plurality of person images includes the eye area of the target person.
