Face recognition method based on twin neural network

The embodiment of the invention provides a face recognition method based on a twinning neural network, the twinning neural network comprises a first neural network and a second neural network which are identical, and the face recognition method comprises the following steps: inputting a first image into the first neural network, the second image is input into a second neural network, and the first image and the second image are obtained by shooting the same object; acquiring a first output result of the first neural network about the first image and a second output result of the second neural network about the second image; and calculating and comparing the first output result and the second output result, and determining target objects of the first image and the second image according to a comparison result. The two images of the same object are calculated and compared through the first neural network and the second neural network to calculate the similarity and difference between the two images, and the tar
