Embodiment Construction

[0049] The present invention is described in detail below in conjunction with examples, but the present invention is not limited to these examples.

[0050] Hyperspectral images are imaged on continuous spectral bands. Compared with traditional RGB images, hyperspectral images are multi-channeled in the spectral dimension, forming a space that not only has spatial image information, but also includes information on any pixel of each image. Data cube for spectral information.

[0051] A spectrum is relative to a substance, similar to a fingerprint relative to a person, and a specific spectrum corresponds to a specific substance, so real faces and camouflage materials have different spectral characteristics.

[0052] On the one hand, if figure 1 As shown, the embodiment of the present invention provides a hyperspectral face recognition method, the method includes:

[0053] S1. Obtain a hyperspectral image and a high-resolution RGB image of a human face. The resolution of the h...

Abstract

The invention discloses a hyperspectral face recognition method and system, belongs to the technical field of public safety, and can solve the problems that the face recognition precision is poor in a complex illumination environment, and an existing face recognition system does not have an anti-counterfeiting function. The method comprises the following steps: acquiring a hyperspectral image and a high-resolution RGB image of a human face; extracting a characteristic spectrum segment image containing human face biological characteristics in the hyperspectral image to obtain an accurate human face region in the hyperspectral image; performing feature positioning and edge contour feature point correction on the accurate face region to obtain a corrected image; the high-resolution RGB image and the corrected image are fused, and a fused image is obtained; and comparing the spectral feature data with data in a face anti-counterfeiting database, and outputting a comparison result.

Description

technical field [0001] The invention relates to a hyperspectral face recognition method and system, belonging to the technical field of public security. Background technique [0002] Face recognition technology is one of the most representative technologies in the field of artificial intelligence. It mainly completes identity recognition by extracting feature information of faces and matching them with faces in the database. Face recognition technology is widely used in security, access control, finance and new retail industries in current social life. [0003] The current face recognition system has relatively high requirements on lighting conditions and human-machine orientation, and can only collect light intensity information, resulting in poor face recognition accuracy in complex lighting environments, such as strong light, low light or shadow conditions, and does not have Anti-counterfeiting function. Contents of the invention [0004] The invention provides a hype...
