Accurate and rapid identification of tea leaf diseases is beneficial to their prevention and control. This study proposes a method based on an improved deep convolutional neural network (CNN) for tea leaf disease identification. A multiscale feature extraction module is added into the improved deep CNN of a CIFAR10-quick model to improve the ability to automatically extract image features of different tea leaf diseases. The depthwise separable convolution is used to reduce the number of model parameters and accelerate the calculation of the model. Experimental results show that the average identification accuracy of the proposed method is 92.5%, which is higher than that of traditional machine learning methods and classical deep learning methods. The number of parameters and the convergence iteration times of the improved model are significantly lower than those of VGG16 and AlexNet deep learning network models. (C) 2019 Elsevier Inc.
