Embodiment Construction
[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0030] In order to better apply the deep learning model in the small-sample iris field, reduce overfitting, and improve recognition accuracy, such as figure 1 As shown, the present invention proposes a method for constructing a small-sample classification model based on transfer learning, which includes the following steps:
[0031] Step 1: Construct ICP-VGG model based on VGG16 model migration learning
[0032] (1) Use the VGG16 model that has been pre-trained on the large dataset ImageNet (including 1.4 million pictures) and denote it as P-VGG16. The initial input size of the model is 224*224, a...
