Selection of image in which both clothing and face of target person are visible
The information processing includes: an acquisition unit for acquiring an image including a face image of a person; and a selection unit for selecting the image in which the part other than the face of a target person is captured among the plurality of images by using the position of the face image of a person other than the target person in the acquired image.
1. An information processing apparatus comprising:
at least one memory storing instructions; and
at least one processor configured to execute the instructions to perform:
acquiring a plurality of images captured by a camera, each captured image including a face image of a target person and a face image of a peripheral person, respectively;
setting an overlap determination area around the face image of the target person;
for each of the plurality of images:
acquiring a first coordinate point that is a center point of a face detection area of the target person;
acquiring a second coordinate point that is closest to the first coordinate point, from among center points of four sides of a face detection area of the peripheral person within the overlap determination area;
calculating a distance between the first and second coordinate points;
selecting, from among the plurality of images captured by the camera, the image with a longest distance between the first coordinate point and the second coordinate point;
comparing the distance between the first and second coordinate points of a previously selected image with the distance between the first and second coordinate points of the selected image;
replacing the previously selected image with the selected image in a case where the distance between the first and second coordinate points of the selected image is longer than the distance between the first and second coordinate points of the previously selected image; and
displaying the selected image on a user terminal.
2. The information processing apparatus according to claim 1 , wherein the processor is configured to select the image in which the face image of the peripheral person is not included in the overlap determination area.
3. The information processing apparatus according to claim 1 , wherein the overlap determination area for each of the plurality of images is set based on a position and size of the face image of the target person in the image.
4. The information processing apparatus according to claim 1 , wherein the processor is configured to select the image based on a positional relationship between the target person and the peripheral person who is in front of the target person.
5. The information processing apparatus according to claim 4 , wherein the processor is configured to compare, for each of the plurality of images, a first size of the face image of the target person with a second size of the face image of the peripheral person in the image, and determine that the peripheral person is in front of the target person when the second size is larger than the first size.
6. The information processing apparatus according to claim 5 , wherein the processor is configured to compare, for each of the plurality of images, a first interocular distance of the target person with a second interocular distance of the peripheral person in the image, and determine that the peripheral person is in front of the target person when the second interocular distance is longer than the first interocular distance.
7. The information processing apparatus according to claim 1 , wherein the processor is configured to repeatedly select the image during a period in which the plurality of images are captured by the camera and acquired.
8. The information processing apparatus according to claim 1 , wherein the processor is further configured to match the face image of the target person with a face image of a person previously registered in a database; and
when the face image of the target person and the face image of the person match, repeatedly select the image during a period in which the plurality of images are captured by the camera and acquired.
9. An information processing method performed by a computer and comprising:
acquiring a plurality of images captured by a camera, each captured image including a face image of a target person and a face image of a peripheral person, respectively;
setting an overlap determination area around the face image of the target person;
for each of the plurality of images:
acquiring a first coordinate point that is a center point of a face detection area of the target person;
acquiring a second coordinate point that is closest to the first coordinate point, from among center points of four sides of a face detection area of the peripheral person within the overlap determination area;
calculating a distance between the first and second coordinate points;
selecting, from among the plurality of images captured by the camera, the image with a longest distance between the first coordinate point and the second coordinate point;
comparing the distance between the first and second coordinate points of a previously selected image with the distance between the first and second coordinate points of the selected image;
replacing the previously selected image with the selected image in a case where the distance between the first and second coordinate points of the selected image is longer than the distance between the first and second coordinate points of the previously selected image; and
displaying the selected image on a user terminal.
10. A non-transitory storage medium storing a program that is executable by a computer to perform processing comprising:
acquiring a plurality of images captured by a camera, each captured image including a face image of a target person and a face image of a peripheral person, respectively;
setting an overlap determination area around the face image of the target person;
for each of the plurality of images:
acquiring a first coordinate point that is a center point of a face detection area of the target person;
acquiring a second coordinate point that is closest to the first coordinate point, from among center points of four sides of a face detection area of the peripheral person within the overlap determination area;
calculating a distance between the first and second coordinate points;
selecting, from among the plurality of images captured by the camera, the image with a longest distance between the first coordinate point and the second coordinate point;
comparing the distance between the first and second coordinate points of a previously selected image with the distance between the first and second coordinate points of the selected image;
replacing the previously selected image with the selected image in a case where the distance between the first and second coordinate points of the selected image is longer than the distance between the first and second coordinate points of the previously selected image; and
displaying the selected image on a user terminal.
