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 present invention relates to a method and system for distinguishing the definition of an ID card based on face recognition, including step 1, image preprocessing, including first converting a color image into a grayscale image, and then performing noise reduction processing on the grayscale image; 2. Recognize and mark the face in the image; step 3, select the text part in the ID card picture, and then judge the text clarity of this part of the image text information; step 4, save according to the judgment result of the text clarity Clear images for subsequent processing. The invention provides a set of highly automatic, high-precision, and high-reliability detection application programs for the definition of ID card pictures, which not only saves time, but also overcomes the disadvantages of poor stability and unreliable detection results of manual detection.

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...
