Abstract EN
Symptoms of nutrient deficiencies in rice plants often appear on the leaves.
The leaf color and shape, therefore, can be used to diagnose nutrient deficiencies in rice.
Image classification is an efficient and fast approach for this diagnosis task.
Deep convolutional neural networks (DCNNs) have been proven to be effective in image classification, but their use to identify nutrient deficiencies in rice has received little attention.
In the present study, we explore the accuracy of different DCNNs for diagnosis of nutrient deficiencies in rice.
A total of 1818 photographs of plant leaves were obtained via hydroponic experiments to cover full nutrition and 10 classes of nutrient deficiencies.
The photographs were divided into training, validation, and test sets in a 3 : 1 : 1 ratio.
Fine-tuning was performed to evaluate four state-of-the-art DCNNs: Inception-v3, ResNet with 50 layers, NasNet-Large, and DenseNet with 121 layers.
All the DCNNs obtained validation and test accuracies of over 90%, with DenseNet121 performing best (validation accuracy = 98.62 ± 0.57%; test accuracy = 97.44 ± 0.57%).
The performance of the DCNNs was validated by comparison to color feature with support vector machine and histogram of oriented gradient with support vector machine.
This study demonstrates that DCNNs provide an effective approach to diagnose nutrient deficiencies in rice.
