Embodiment Construction
[0024] In this embodiment, the process is as follows figure 1 As shown, a flow chart of image classification network training based on massive single-category single-frame images. The specific implementation mainly includes the following steps:
[0025] Step (1): Data preparation: Use 1 million single-type and single-face ID card datasets as training dataset 1, and use Webface face dataset as training dataset 2.
[0026] Step (2): Data preprocessing: convert the prepared images of the two face datasets into 128*128 resolution.
[0027] Step (3): Alternate cycle training is based on the image classification network of massive single class single image: Mini-batch is the number of data samples processed in each batch of training, and the present invention adopts that the number of training in each batch is 64, when When the number of training iterations is odd, randomly select 64 pictures from dataset 1 without repetition, and input them into the image classification network.
