HUMAN FACIAL DETECTION AND RECOGNITION SYSTEM

Blue Line Security Soluti...

1. A method comprising:receiving, by at least one processor, high-definition video data from at least one camera associated with a surveillance system, the high-definition data comprising a sequence of images and storing the sequence of images in a database;
detecting, by the at least one processor, at least a portion of a face from the sequence of images;
generating, by the at least one processor, a mapping of facial points corresponding to the at least the portion of the face from the sequence of images by generating a plurality of points on an image plane corresponding to the sequence of images and determining a distance between each point to the plurality of points, each point corresponding to at least one of an edge-like feature of the face and a ridge-like feature of the face;
cross-referencing, by the at least one processor, the mapping of facial points with each facial image of a set of pre-stored and previously recognized facial images to perform one of recognizing the face and not recognizing the face; and
automatically generating, by the at least one processor, information associated with the face and transmitting the information associated with the face.

HUMAN FACIAL DETECTION AND RECOGNITION SYSTEM

Blue Line Security Soluti...

1. A method comprising:receiving, by at least one processor, live, high-definition video data from at least one camera, the high-definition data comprising a sequence of images and storing the sequence of images in a database;
detecting, by the at least one processor, at least a portion of a face from the sequence of images;
generating, by the at least one processor, a mapping of facial points corresponding to the at least the portion of the face from the sequence of images by generating a plurality of points on an image plane corresponding to the sequence of images and determining a distance between each point to the plurality of points, each point corresponding to at least one of an edge-like feature of the face and a ridge-like feature of the face;
cross-referencing, by the at least one processor, the mapping of facial points with a set of pre-stored and previously recognized facial images to identify a match, the match identified when a match rate percentage is greater than a particular percentage; and
triggering, by the at least one processor, an alert of the match and transmitting the alert for display to a computer device.

HUMAN FACIAL DETECTION AND RECOGNITION SYSTEM

Blue Line Security Soluti...

1. A method for detecting faces comprising:detecting, using one or more computing devices, at least a portion of a face from at least one image of a sequence of images by applying a plurality of image strips to the sequence of images, the plurality of image strips together forming a particular curvature and a particular pattern, each image strip of the plurality of image strips having a same width, and determining at least one of an edge-like feature of the face and a ridge-like feature of the face by:
generating, using the one or more computing devices, a mapping of facial points corresponding to the at least one image by:
generating a plurality of points on an image plane corresponding to the at least one image and determining a distance between each point to the plurality of points, each point corresponding to the at least one of the edge-like feature of the face and the ridge-like feature of the face;
projecting the plurality of points from the image plane to a surface of a face model;
mirroring the plurality of points using facial symmetry;
identifying, using the one or more computing devices, a match for the mapping of facial points by comparing the distance between each point to the plurality of points and the mapping of facial points to a recognized image stored in a database; and
triggering, using the one or more computing devices, an alert of the match and transmitting the alert for display to a user computer device.
