Abstract

The present disclosure provides a face image screening method and device. The face image screening method includes: intercepting the face image to be processed in the picture according to the face recognition task; outputting the fuzzy value and brightness value of the face image to be processed through a preset neural network; Determining a fuzziness threshold and a brightness threshold; marking a human face image to be processed whose fuzziness value is greater than the fuzziness threshold and whose brightness value is greater than the brightness threshold as a clear image. The method for screening human face images provided by the present disclosure can overcome the influence of race on the screening of portrait pictures.

Description

technical field [0001] The present disclosure relates to the technical field of face recognition, and in particular, to a face image screening method and device. Background technique [0002] The wide application of face recognition has strict requirements on the security and stability of the technology, but the face recognition algorithm is easily affected by factors such as illumination, angle, occlusion and clarity, and the quality of the collected face images seriously affects the application system. performance. Due to factors such as lighting, motion, and out-of-focus, the acquired face images will be distorted to varying degrees. For example, low-quality face images that are too dark or too blurred will greatly affect the performance of the face comparison algorithm, causing high-probability errors. identify. At the same time, low-quality face images will lead to an increase in the number of comparison failures, resulting in a waste of computing resources, especiall...
