See full text

A face image detection method includes: recognizing facial features of a face image, and determining two pupil centers of the face image; connecting the two pupil centers, and determining a center point of a line segment whose endpoints are the two pupil centers; and selecting K columns of pixels from a local image region including the center point, calculating a gradient value of each pixel in each column of pixels, and generating K gradient vectors including gradient values of all columns of pixels, determining, based on a result of comparing the K gradient vectors with a specified threshold, whether glasses are worn on the face image.
