Bird image classification based on improved ResNet-152 image classification model

Bird image classification is an important research direction in the field of computer vision, and its main purpose is to automatically identify bird images through computers to achieve bird classification, recognition and monitoring. Birds are an important part of the planet's biodiversity and have an important impact on the balance of ecosystems and human survival. ResNet-152 is a deep convolutional neural network model, which is the deepest model in the ResNet family, with a depth of 152 layers. The model mainly solves the problems of gradient vanishing and gradient explosion in deep neural networks through residual learning, and improves the accuracy and generalization ability of the network. The ResNet-152 model has achieved good results in the fields of image classification, object detection and semantic segmentation. For the bird classification dataset BIRDS 525 SPECIES-IMAGE CLASSIFICATION, the ResNet-152 model was used for classification, and excellent results were obtained. The classification accuracy reached 96.5%, the accuracy reached 98.0%, the recall rate was 94.6%, the f1 score was 94.7%, and the AUC reached 95.6%. These indicators indicate that the ResNet-152 model has high classification accuracy and generalization ability for bird classification datasets. At the same time, it also shows that the ResNet-152 model has a good application prospect in processing large-scale image classification tasks.
