Abstract
A light source (11) of a disguising mask detecting device (1) emits light at a person who is a subject. A camera (12) acquires images in multiple different wavelength ranges of reflected light of the light emitted at the person. A face detector (172) detects a face region of the person from the images acquired by the camera (12). A determiner (173) determines that the person is wearing a disguising mask when luminances of the face region in the images satisfy specific relations different from relations exhibited by skin.
Claims10
A detecting device comprising:
- at least one memory configured to store instructions;
- and
- at least one processor configured to execute the instructions to:
- acquire a visible light image including a face region of a person;
- acquire an infrared light image in an infrared wavelength range;
- detect the face region of the person in the visible light image;
- and
- determine whether the person is disguised with the silicon mask based on the infrared light image.
A method of detecting comprising:
- acquiring a visible light image including a face region of a person;
- acquiring an infrared light image in an infrared wavelength range;
- detecting the face region of the person in the visible light image;
- and
- determining whether the person is disguised with the silicon mask based on the infrared light image.
A non-transitory computer readable medium having stored therein a program for performing a method, the method comprising:
- acquiring a visible light image including a face region of a person;
- acquiring an infrared light image in an infrared wavelength range;
- detecting the face region of the person in the visible light image;
- and
- determining whether the person is disguised with the silicon mask based on the infrared light image.
