Problems solved by technology
[0003] However, there are still many loopholes in the face recognition system. System loopholes mainly include video playback attacks, feature masquerading attacks, and attacks using biosensors, etc.
Once face recognition fails, the user's personal information will be exposed, which will bring hidden dangers to property safety

The invention discloses a living body discriminating detection method based on an infrared camera. The living body discriminating detection method comprises the following steps of S1, using the infrared camera for shooting a background behind a person to be detected; S2, shooting the human face of the person to be detected and the background around the human face by using the infrared camera; S3,comparing the background around the human face with the background behind the human body to be detected, and performing preliminary judgment on the human face living body; S4, carrying out multi-colorspace conversion on the face photo, carrying out the feature extraction, and obtaining a space image; S5, processing the texture information of the space image, and processing the texture intensity of the space image; S6, carrying out noise reduction processing on the spatial image, and then carrying out the normalization processing; S7, inputting the data after the normalization processing in the step S6 into a multi-level neural network, and constructing a face information set by training the multi-level neural network; S8, comparing the face information set with THE face information storedin the system; and S9, outputting a judgment result.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a living body detection method based on an infrared camera. Background technique [0002] With the advancement of science and technology, face recognition technology is increasingly being applied to people's lives. People can use face recognition technology to unlock mobile phone locks, consumer payments, access control unlocking and electronic transactions, etc. It benefits from the unique biological characteristics of the human body. Each organism has special and irreplaceable biological characteristics. The computer system can perform calculations based on human biological characteristics to achieve the purpose of characteristic recognition. Human physiological characteristics include fingerprints, voices, palm prints and irises, etc. In particular, face recognition and fingerprint recognition technologies have been successfully developed in the market. [0003] However, ther...
