| titleOfInvention | A method and system for rapid living detection |
| abstract | The invention discloses a method and a system for rapid living body detection, belonging to the field of living body detection. By constructing the spectrogram of the real face image and the multi-scale and multi-rotation angle of the second-shot face image, and using the projection vectors of the spectrogram in the horizontal and vertical directions as the feature vector, the moiré pattern of the image can be fully extracted. Features, without relying on complex neural network structure, to achieve rapid detection of video replay attack methods. The blood volume distribution is constructed by using the correlation between the overall facial signal of the face image and the local signal of interest. On this basis, the frequency peak distribution is calculated. Combined with the threshold segmentation model, the precise positioning of the area containing the physiological signal is realized, which can be used for high simulation. High-precision detection of mask and high-definition image attacks. The present invention does not need to specify facial actions to cooperate with detection, and can perform comprehensive detection only by collecting facial video, covering the main living body detection attack methods, and has high detection accuracy and detection speed. |
