METHOD OF IDENTIFYING EYES ON IMAGES AND DEVICE FOR IMPLEMENTING SAID METHOD Russian patent published in 2010 - IPC G06K9/62 G06K9/78 G06T1/00 

FIELD: physics.

SUBSTANCE: invention can be used in automated vision diagnosis systems, in digital photographic cameras for avoiding portrait photographs with closed eyes and for solving other practical tasks. In the method of identifying eyes, values of eye identification features which are invariant to shift, turning and change in scale are calculated, values of a reduced set of features for preliminary classification of objects and the range of values of features for identifying open and closed eyes are determined, the state of the eyes is detected using the said set of features. The device for identifying eyes has an eye edge detection unit, a bus controller, a microprocessor, RAM for storing intermediate image processing results, a unit for determining the state of the eyes and an eye position detection unit. The device enables to find eyes of a person or group of people on a digital image regardless of the position of the person in the plane of the frame (invariant to shift, turning of the face image in the plane of the frame), and is also sensitive to change in distance to a person and, as a result, to change in scale of the eyes on the image; reliable identification is provided at linear dimensions of the eyes of 40 or more points.

EFFECT: more accurate identification of eyes of a person on an image and increased versatility of the method due to use of general eye description.
