The invention relates to a
crop disease identification method based on
wavelet transform and residual network fusion. According to the method, a CBAM attention mechanism,
wavelet transform and a residual network are fused, and a
disease identification model (CropNet) for non-specified
crop types is provided. According to the CropNet, firstly, Haar wavelets are utilized to perform four-stage
decomposition on
disease images,
frequency domain features are deeply extracted, and the
frequency domain features and spatial features extracted by a residual network are continuously fused; then different weights are given to the fused feature layer by using CBAM, and the attention of the model to a
disease area is increased; and finally, a dual transfer learning training model is utilized to improve the accuracy and generalization of the model for identifying diseases of non-specified
crop types. The identification accuracy of the CropNetA is 99.76%, the identification accuracy of the CropNetA is 99.85%, and the identification accuracy of the CropNetA is 99.86% on the PlantVillage
data set, the identification accuracy of the CropNetA is 99.85% on the AI Challenger 2018
data set and the identification accuracy of the CropNetA on the self-built
data set. The result shows that the method can obtain clearer and more sufficient
disease characteristics while reducing the
noise, improves the disease recognition precision, and provides reference for intelligent
agriculture and precise recognition, prevention and control of crop diseases.
