Embodiment Construction
[0045] In this embodiment, a near-infrared-visible light face image synthesis method based on contrastive learning and StyleGAN2, refer to figure 1 : First collect near-infrared-visible light face images from different people, and preprocess the data set to obtain training set images; introduce a contrastive learning mechanism to build a generator, discriminator, and image multi-layer features based on the StyleGAN2 structure Generate a network model including the extracted block; combine the appropriate loss function and optimization function, use the training set image to train the generated network model; input the near-infrared face image to be tested to test the model, and finally synthesize the corresponding visible light face image.
[0046] Specifically, proceed as follows:
[0047] Step 1. Collect paired near-infrared-visible light face images and perform unified face detection and normalization preprocessing to obtain dataset images;
[0048] Step 1.1, using an opti...
