Embodiment Construction

[0054] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] figure 1It is a flowchart of an embodiment of the present invention, figure 2 For the ID card picture example, adopt the flow chart of the embodiment of the present invention to process the ID card picture example as follows:

[0056] 1. Image preprocessing:

[0057] First convert the color image into a grayscale image, and then use the median filter and Gaussian filter for noise reduction.

[0058] 2. Recognize and mark faces in images

[0059] 2.1 Face recognition: use Haar classifier to recognize faces. The Haar feature classifier is an XML file in the project, which describes the Haar feature values ​​of various parts of the human body, including faces, eyes, lips, and so on. Load the Haar feature classifier into the project to recognize faces in pictures.

[0060] 2.2 Face marking: Use a rectangular frame to...

Abstract

The invention relates to a face recognition-based identity card definition discrimination method and system. The method comprises the following steps of: 1, image preprocessing: converting a color mapinto a greyscale map and denoising the greyscale map; 2, recognizing and marking a face in an image; 3, selecting a character part in an identity card picture and discriminating character definitionof image character information of the part; and 4, storing clear image according to the definition discrimination result so as to be used by subsequent processing. According to the method and system,an identity card picture definition detection application program which is high in automation, high in precision and high in reliability is provided, so that the time is shortened, and the malpracticethat the manual detection is bad in stability and unreliable in detection result is overcome.

Description

technical field [0001] The invention belongs to the field of face recognition, is applied to judging the sharpness of photographed ID card pictures, and relates to a character sharpness judging technology based on face recognition. Background technique [0002] In recent years, with the continuous advancement of digital financial technology, electronic payment has gradually integrated into all aspects of people's daily life. The online payment platform requires the user to upload a photo of the ID card to obtain the user's identity information, complete the user's identity verification and protect the interests of legitimate users. Therefore, as the basis for information acquisition, the clarity of ID card pictures determines whether authentic and reliable information can be obtained, which is also an important link in online payment and transactions. The traditional method of judging the sharpness is to use manual detection, which wastes a lot of manpower and does not meet...
