Each year, plant diseases cause considerable damages to the agricultural sector which their effect on the economy and food security is very important. Early detection of plant diseases is a useful strategy to reduce these losses. In recent years, researchers have used a variety of techniques such as machine vision for the diagnosis of plant diseases. In this study, a new system, consisting of digital image processing technique and also combination model of artificial neural network to distinguish three apple tree leaf diseases (namely Alternaria, apple black spot, and apple leaf miner pest) were used. In short, the process of digital image processing technique involves preparation, processing, and extraction of features of each of the sample images and the hybrid artificial neural network model was used to classify diseases. In this model, particle swarm optimization algorithm for network training (PSO) and Levenberg-Marquardt (LM) were used. After that, the operation of the proposed system for diagnosis of diseases of apple trees was evaluated. It is concluded that the system has a good performance for diagnosis accuracy was 99% and R2=0.985, RMSE=0.099. Finally, in comparison with other methods mentioned by other researchers for diagnosis of apple tree leaves diseases, the proposed system has higher ability.
