Problems solved by technology

[0004] However, the applicant found that in a backlit scene, when the above-mentioned method is used to acquire an image, since the background brightness of the portrait is very strong, the automatic exposure control system will be affected by the background brightness, resulting in a relatively weak brightness gain for controlling the entire image. As a result, the portrait area in the final acquired image is still dark, which makes the success rate of face recognition still relatively low, affecting user experience

Embodiment Construction

[0026] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0027] In order to solve the problem in related technologies, when the image is captured by the automatic exposure control system in a backlit scene, since the background brightness of the portrait is very strong, the automatic exposure control system will control the brightness gain of the entire image to be relatively weak due to the influence of the background brightness , resulting in darker portrait area in the finally acquired image, which makes the success rate of face recognition still relatively low and affects the u...

Abstract

The application discloses a human face recognition method, device, equipment and storage medium. The method comprises the following steps: determining a brightness histogram corresponding to a currentimage when a human face recognition instruction is acquired; adjusting the brightness of all pixels in the current image according to the brightness histogram to obtain a target image; carrying out human face recognition on the target image. According to the method disclosed by the application, the brightness of the image is adjusted according to an image brightness histogram for brightening a partially-dark human face area, so that the success rate of human face recognition is improved and user experience is improved.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a face recognition processing method, device, equipment and storage medium. Background technique [0002] At present, face recognition technology is widely used in terminal equipment, security, monitoring and other fields. The accuracy and robustness of face recognition algorithms have become a common standard for measuring face recognition algorithms and related integrated products. [0003] In actual use, the performance of the face recognition algorithm has a strong correlation with the quality of the input image. If the quality of the input image is not good, the performance of the face recognition algorithm will be greatly reduced, thereby affecting the final recognition rate. For this reason, in the related art, the brightness of the human face is controlled by adopting an automatic exposure control system to ensure that the portrait is highlighted. ...
