Embodiment Construction

[0057]A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art will appreciate that these embodiments are intended to illustrate the technical principles of the present invention, and are not intended to limit the scope of the invention.

[0058]Seefigure 1 ,figure 1 An exemplary showing the main steps of a face recognition method based on a documentary and on-site photo in this embodiment. Such asfigure 1 As shown, the person's face recognition method based on the document and the scene in this embodiment may include the following steps:

[0059]Step S101: Get the ID image of the target and the scene photo image.

[0060]In this embodiment, the document illuminates the person's face image on the ID card, driver's license or agency guarantee, and the document image has a monochrome background, the normal light and the nature of the human face expression. On-site image refers to face images under random envir...

Abstract

The invention relates to the technical field of biological feature recognition, specifically provides a face recognition method and system based on ID photos and on-site photos, and aims to solve the technical problem of how to improve the accuracy of face recognition based on ID photos and on-site photos. For this purpose, the face recognition method in the present invention can calculate the similarity of the two according to the image features of the ID photo image and the on-site photo image, and then judge whether the ID photo image and the on-site photo image are similar according to the similarity value. Based on this, when comparing large-scale ID photos with on-site photos, based on the similarity judgment, the image comparison can be quickly completed. Meanwhile, the face recognition system in the present invention can execute and realize the above face recognition method.

Description

Technical field[0001]The present invention relates to the field of biomechanical identification, and more particularly to a human face recognition method and system based on a documentary and on-site photo.Background technique[0002]Face recognition technology refers to the use of computer methods to identify people's face technology, which mainly includes the following steps: First, it is judged whether there is a face in a face image or video stream, and if there is a face, it will get everyone's face. Location, size and location information of each major facial organ. The identity feature included in each face is extracted according to the acquired information. Finally, the extracted identity feature is compared with the preset human face characteristics, thereby identifying the identity of each face based on the alignment results.[0003]At present, face recognition technology based on machine learning algorithms requires learning a large number of sample data to improve the recogn...
