A Face Verification Method Based on Identity Document Information

Abstract

The invention discloses a face verification method based on identity document information. The method performs on the electronic image A of the chip information of the identity document, the face image B on the surface of the identity document, and the face image C collected in real time; The comparison of B, and the comparison of the chip information text W1 and the certificate surface text W2, to judge the authenticity of the certificate; and then by comparing the images B and C, to judge whether the person and the certificate are one; due to the long validity period of the ID card , in a long time span, there may be a large difference between the ID card holder and the photo of the ID card, which greatly affects the accuracy of the verification; the present invention proposes a spectrum sampling with strong robustness to the time span Structural subspace feature algorithm is used for face verification. Through this algorithm, the face image on the surface of the ID card is compared with the real-time collected face photos for recognition, which has the advantage of effectively improving the recognition rate.

Description

technical field [0001] The invention belongs to the field of image processing, and more specifically relates to a face verification method based on identity document information. Background technique [0002] The current second-generation ID card has a built-in non-contact IC smart chip, which stores the face image information of the ID card holder and the identity information of the ID card holder; the surface of the ID card is printed with the ID card holder's Face image and identity information. The existing ID card face verification system uses the face image stored in the ID card chip to compare with the face image collected by the ID card holder on site for identity verification; because the resolution of the image stored in the ID card chip is too low (Only 102×126 pixels), there is a possibility of misjudgment. [0003] Patent document CN 104021397 A discloses an identity verification system based on second-generation identity documents and face feature recognition...

[0003] Patent document CN 104021397 A discloses an identity verification system based on second-generation identity documents and face feature recognition, which uses Gabor filters to filter and transform face images to obtain Gabor features, and then uses face image feature vectors and identity document person Face image feature vectors, multiple Markov models are established, and the matching results are obtained by calculating the likelihood value corresponding to each Markov model; the system improves the accuracy of identity verification, but the system does not verify identity documents The authenticity of the identity card and the long-term span of the holder have not been dealt with; when the ID card has a long time span and the facial features of the holder change over time, the recognition rate is low
