Abstract
Exemplary image calibration systems and methods are described herein. An exemplary method includes an image calibration system receiving data representative of an input camera image, detecting a face of a person represented in the input camera image, determining a predefined skin tone template associated with the person, and modifying the input camera image to change an appearance of the face of the person based on the predefined skin tone template associated with the person. In certain embodiments, the modification changes one or more skin tones represented by an image of the face of the person in the camera image based on the predefined skin tone template. Corresponding methods and systems are also disclosed.
Claims23
A method comprising:
- receiving, by an image calibration system, data representative of an input camera image;
- detecting, by the image calibration system, a face of a person represented in the input camera image;
- determining, by the image calibration system, a predefined skin tone template associated with the person;
- and
- modifying, by the image calibration system, the input camera image to change an appearance of the face of the person based on the predefined skin tone template associated with the person.
A method comprising:
- receiving, by an image calibration system, data representative of a calibration camera image that includes an image of a face of a person;
- detecting, by the image calibration system, a user request to create a skin tone template for the person based on the calibration camera image;
- generating, by the image calibration system in response to the user request, the skin tone template for the person based on the calibration camera image by obtaining image data for one or more regions of the face of the person from the calibration camera image and storing the image data in the skin tone template;
- receiving, by the image calibration system, data representative of an input camera image;
- detecting, by the image calibration system, an image of the face of the person in the input camera image;
- identifying, by the image calibration system, the person from the image of the face of the person in the input camera image;
- accessing, by the image calibration system, the skin tone template for the person;
- and
- modifying, by the image calibration system, data representative of the image of the face of the person in the input camera image based on the skin tone template for the person to produce a calibrated camera image.
A system comprising:
- a processor;
- and
- a skin tone calibration facility configured to direct the processor to:
- detect an image of a face of a person in a camera image,
- determine a predefined skin tone template associated with the person, and
- modify data representative of the image of the face of the person in the camera image based on the predefined skin tone template associated with the person.
