Abstract
Rice is a staple food for roughly half of the world’s population. Some farmers prefer
rice cultivation to other crops because rice can thrive in a wide range of environments. Several
studies have found that about 70% of India’s population relies on agriculture in some way and
that agribusiness accounts for about 17% of India’s GDP. In India, rice is one of the most important
crops, but it is vulnerable to a number of diseases throughout the growing process. Farmers’ manual
identification of these diseases is highly inaccurate due to their lack of medical expertise. Recent
advances in deep learning models show that automatic image recognition systems can be extremely
useful in such situations. In this paper, we propose a suitable and effective system for predicting
diseases in rice leaves using a number of different deep learning techniques. Images of rice leaf
diseases were gathered and processed to fulfil the algorithmic requirements. Initially, features were
extracted by using 32 pre-trained models, and then we classified the images of rice leaf diseases such
as bacterial blight, blast, and brown spot with numerous machine learning and ensemble learning
classifiers and compared the results. The proposed procedure works better than other methods that
are currently used. It achieves 90–91% identification accuracy and other performance parameters
such as precision, Recall Rate, F1-score, Matthews Coefficient, and Kappa Statistics on a normal
data set. Even after the segmentation process, the value reaches 93–94% for model EfficientNetV2B3
with ET and HGB classifiers. The proposed model efficiently recognises rice leaf diseases with an
accuracy of 94%. The experimental results show that the proposed procedure is valid and effective
for identifying rice diseases.
