Severity Recognition of Aloe Vera Diseases Using AI in Tensor Flow Domain

Agriculture plays an important role in the economy of all countries. However, plant diseases may badly affect the quality of food, production, and ultimately the economy. For plant disease detection and management, agriculturalists spend a huge amount of money. However, the manual detection method of plant diseases is complicated and time-consuming. Consequently, automated systems for plant disease detection using machine learning (ML) approaches are proposed. However, most of the existing ML techniques of plants diseases recognition are based on handcrafted features and they rarely deal with huge amount of input data. To address the issue, this article proposes a fully automated method for plant disease detection and recognition using deep neural networks. In the proposed method, AlexNet and VGG19 CNNs are considered as pre-trained architectures. It is capable to obtain the feature extraction of the given data with fine-tuning details. After convolutional neural network feature extraction, it selects the best subset of features through the correlation coefficient and feeds them to the number of classifiers including K-Nearest Neighbor, Support Vector Machine, Probabilistic Neural Network, Fuzzy logic, and Artificial Neural Network. The validation of the proposed method is carried out on a self-collected dataset generated through the augmentation step. The achieved average accuracy of our method is more than 96% and outperforms the recent techniques.
