Abstract

The invention discloses a method and a device for locating human eyes. The method for locating the human eyes comprises the steps of receiving a human face image; locating the nose position and eye positions in the human face image; determining a human face symmetry shaft according to the nose position; adjusting the eye positions according to the human face symmetry shaft, and obtaining target location positions of the human eyes. According to the method and the device, disclosed by the invention, the problem of poorer human eye location accuracy in the prior art is solved, and thus the effect of increasing the eye location accuracy is achieved.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to a human eye positioning method and device. Background technique [0002] In general, a complete face recognition system is composed of four parts: face detection, eye positioning, feature extraction and face recognition. In the recognition process, whether using the global features or local features of the face, using the geometric features or algebraic features of the image, the change of the face orientation has a significant impact on the recognition results, so it is necessary to perform image recognition before recognition. Perform normalization. The condition for image normalization is the position of the eyes, the specific reasons are as follows: [0003] 1) The distance between the centers of the two eyes is least affected by changes in illumination and expression, and the direction of the line connecting the centers of the two eyes is deflected with the deflecti...
