Abstract

Timely and accurate identification of peach tree pests and assistance in pest control is the key to promoting the healthy development of the peach industry. A lightweight peach tree pest image recognition model based on global context modeling is proposed for existing pest image recognition models with high structural complexity, high dependence on computational resources at runtime, and deployment difficulties. First, a lightweight global context modeling module is embedded in the ShuffleNet V2 unit to aggregate all the location information of the input image, obtain global context features, correct the pest information, and improve the feature representation capability of the model. Then, the ordinary convolution layer of ShuffleNet V2 is optimized to add lightweight convolution to improve the feature extraction ability of the model at different stages. Finally, a softmax classifier is connected to obtain a lightweight peach tree pest image recognition model. After experimental verification, the proposed model outperforms neural networks such as AlexNet in terms of recognition accuracy, parameter computation and floating point operation, and the number of parameters is only one-tenth or even a few tenths of AlexNet, which is a lightweight and efficient neural network model that can be easily deployed.
