Embodiment

[0027] In an embodiment, a method for automatic face detection and recognition based on a backlight environment of the present invention includes:

[0028] A step of obtaining human face template information data by using the skin color model constructed under normal lighting environment;

[0029] The step of saving the face template information data in a designated database;

[0030] The step of collecting the face video image of the object to be tested by using the video input device;

[0031] Process the human face video image and determine whether the human face video image belongs to the step of obtaining under the backlight environment;

[0032] The step of performing backlight compensation processing on the face video image;

[0033] A step of comparing and judging the face video image data of the subject to be tested after backlight compensation and the face template information data.

[0034] According to the method of automatic face detection and recognition based...

Abstract

The invention discloses a method for automatically detecting and identifying face on the basis of the backlight environment. The method comprises the following steps of: obtaining the face template information data by using a complexion model constructed under the normal lighting environment; preserving the face template information data in a specified database; collecting a face video image of an object to be tested by using a video input device; processing the face video image and judging whether the face video image is obtained in the backlight environment; performing backlight compensation processing on the face video image; and comparing and judging the face video image data of the object to be tested with the data of the face template information. In the invention, the face video image of the object to be tested is compared with the face template information data under the normal lighting environment without influence of the backlight environment through backlight compensation of the collected face video image of the object to be tested on the basis of judgment of the backlight environment so that the detection and identification of face can be correctly judged.

Description

technical field [0001] The invention relates to a face detection and recognition technology, in particular to a face automatic detection and recognition method based on a backlight environment. Background technique [0002] With the rapid development of the national economy and the substantial improvement of people's living standards, criminal activities of hostile forces at home and abroad are becoming increasingly rampant. Economic, criminal and international terrorism and other crimes are being hit hard, and the struggle of "chasing, escaping and blocking" is being carried out jointly. Among them, how to identify the identity of the suspect is the key to the success of this struggle. At present, most of the methods used are to publish or post the photos, ID cards, and characteristic data of criminal suspects on the Internet. However, the identification of this method needs to pass through a variety of technical appraisals, and it has a greater impact on the inquiry of fa...
