Abstract
A vision-based operating system is provided in which a computer-based system accepts visual inputs and takes appropriate actions in a wide variety of environments. One environment is a security environment in which the vision-based operating system acquires an image of a face and determines, with an arbitrarily small probability of a false positive, whether the face is of a person who is authorized to enter the environment.
Claims71
A method of determining whether an acquired image matches a reference image, comprising:
- acquiring a digital image for comparison to a reference image;
- identifying a group of pixels in the acquired image;
- selecting the pixel group in the reference image that is the best match for the pixel group in the acquired image;
- repeating the preceding steps for at least one more group of pixels;
- comparing the relative locations of the selected pixel groups in the reference images and the pixel groups in the acquired image;
- and
- determining the probability that the relative locations occurred randomly.
A processor-based system having an image based-operating system, comprising:
- a camera, located in an environment;
- and
- a computer-based system in data connection with the camera, the computer-based operating system having an operating system that is capable of operating the computer-based system in response to image data acquired by the camera.
A method, comprising:
- locating a camera in an environment;
- capturing an image of the environment, the image comprising an image of an event of the environment;
- providing a vision-based operating system for processing the image;
- processing the image to identify a characteristic of the event;
- and
- taking an action based on the characteristic.
A system for determining whether an acquired image matches a reference image, comprising:
- a camera for acquiring a digital image for comparison to a reference image;
- an identification module for identifying a group of pixels in the acquired image;
- a selection module for selecting the pixel group in the reference image that is the best match for the pixel group in the acquired image;
- a comparison module for repeating the preceding steps for at least one more group of pixels and for comparing the relative locations of the selected pixel groups in the reference images and the pixel groups in the acquired image;
- and
- a calculator for determining the probability that the relative locations occurred randomly.
A method of providing a processor-based system having an image based-operating system, comprising:
- locating a camera in an environment;
- and
- providing a computer-based system in data connection with the camera, the computer-based operating system having an operating system that is capable of operating the computer-based system in response to image data acquired by the camera.
A vision-based system, comprising:
- a camera in an environment for capturing an image of the environment, the image comprising an image of an event of the environment;
- a vision-based operating system for processing the image to identify a characteristic of the event;
- and
- an actuator for taking an action based on the characteristic.
