Embodiment Construction

[0043] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] The present invention provides an illumination adaptive face recognition method, referring to figure 1 , in one embodiment, the illumination adaptive face recognition method includes:

[0045] Step S10, collecting multiple face pictures, and saving the acquired face pictures to the corresponding database according to the level of light intensity;

[0046] The illumination-adaptive face recognition method provided by the embodiment of the present invention is applied in a face recognition system to recognize a currently captured face picture. Specifically, in one embodiment, multiple face pictures can be taken by a video camera or camera and other imaging equipment to form a training sample, and then the basic facial features of the face in the training sample and the facial features that exist due to differenc...

Abstract

The invention discloses a light-adaptive facial recognition method, comprising the steps of acquiring multiple facial images, and storing the acquired multiple facial images to corresponding databases according to light intensity levels; acquiring self-similarity of test samples under current light intensity according to the facial mages in the database corresponding the current light intensity level and the currently taken test samples; calculating optimal thresholds of image characteristics of the test samples under the current light intensity; comparing the self-similarity of the test samples under the current light intensity to the optimal thresholds of image characteristics so as to determine classification results of the test samples. The invention also discloses a light-adaptive facial recognition system. Light-adaptive adjustment of optimal thresholds is achieved, more accurate facial recognition classification results are provided, and therefore the facial recognition system is more stable.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to an illumination adaptive face recognition method and system. Background technique [0002] Face has the advantages of rich features and convenient collection. Compared with other biological features, it is unique and irreproducible. As one of the identification technologies, face recognition is widely used in public security, online payment and employee attendance. At present, in face recognition technology, unregistered users are often excluded by setting a threshold, but in actual application scenarios, the actual threshold of the face recognition system often changes with changes in the lighting scene, resulting in inaccurate recognition results, thus affecting This improves the stability of the face recognition system. Contents of the invention [0003] The main purpose of the present invention is to provide an illumination adaptive face recognition method and sys...
