“…Convolutional neural networks, as an important member of image classification algorithms, have the advantages of high recognition accuracy, fast detection speed, and great development potential [ 12 ], have achieved considerable success in image classification [ 13 ], object detection [ 14 ], pose estimation [ 15 ], image segmentation [ 16 ], and face recognition [ 17 , 18 ], have great scaling advantages [ 19 ], and have been widely used in agriculture [ 20 ], healthcare [ 21 ], education [ 22 ], energy [ 23 ], industrial inspection [ 24 ], and other fields [ 25 ]. Currently, convolutional neural networks have been used for tea tree pest and disease identification [ 26 ], tea grade sieving [ 7 ], and the sorting of tea tree fresh leaves [ 8 ], but for the recognition and classification of different species of green tea based on ResNet, a typical convolutional neural network is proposed by researchers in recent years to perform computer vision tasks, which minimizes the gradient disappearance problem caused by increasing the depth of the network due to the introduction of the residual module and reduces the redundancy of information in the data while maintaining a high accuracy rate, which is simple and practical.…”
