Abstract

An embodiment of the invention discloses a glasses elimination method for face recognition to solve the problem that the glasses of a face image reflect light. The method disclosed by the embodiment of the invention comprises the following steps: acquiring a face image, and carrying out gray-scale treatment on obtained multiple image frames to obtain multiple first images; carrying out face detection on the first images to obtain a face region; calculating the reflectance of the face region; screening the first images of which the reflectance is not greater than a preset first reflectance threshold as second images; positioning a glass frame region of a glass frame on the second images; and restoring the glass frame region on the second images to obtain a target image without the glass frame.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a method for removing glasses for face recognition. Background technique [0002] Illumination, posture and expression are the main factors affecting face recognition, among which illumination changes have a greater impact on face recognition. Near-infrared images can effectively solve the impact of environmental light changes, but the near-infrared active light source illuminates the glasses to form reflections that will cause human eye positioning failure. In addition, the occlusion of the glasses frame will also affect the accurate positioning of feature points and cause a decline in recognition rate. . [0003] The reflection problem of face image spectacle lenses is a long-standing technical problem in the field of face recognition. At present, there is no effective solution at the image processing level. Contents of the invention [0004] An embodiment of the p...
