CNN-Based Classification of Nutrient Stress in Rice Using Leaf Images

PosterSakuraBeginnerEN

This project presents a deep learning-based approach for classifying the phosphorus status of rice leaves using digital images. Convolutional neural networks were used to detect subtle visual patterns associated with phosphorus deficiency, enabling non-invasive diagnosis at the leaf level. The workflow was implemented entirely in Python, combining image preprocessing (OpenCV), model training (TensorFlow), and performance evaluation (scikit-learn). Preliminary results showed that CNNs can accurately distinguish between healthy and phosphorus-deficient leaves, demonstrating the potential of AI-powered tools in agricultural diagnostics.


Description

The poster will show how deep learning with Python can detect phosphorus deficiency in rice plants using leaf images. It presents a practical workflow combining image preprocessing and CNN-based classification to support plant health monitoring. Tools used include OpenCV, TensorFlow, and scikit-learn.


Motivation

As an engineer, I'm interested in innovative applications of AI. This project was a chance to apply computer vision to agriculture by using deep learning to detect phosphorus deficiency in rice leaves.


Key Takeaways

I expect they will learn from my experience in applying CNNs to real-world problems, including data preparation, model training, and evaluation in the context of agricultural diagnostics.


Prerequisites

Basic Python and generally familiar with machine learning ideas like classification and neural networks.

Profile

I graduated as a Systems Engineer in Colombia and worked as a software developer for 12 years. Later, I pursued a master’s degree at Hiroshima University, where I began developing a deep learning model to classify nutrient deficiencies in rice leaves. I completed the degree in March 2025 and started a PhD in April, continuing my research with the goal of refining and expanding the model for broader agricultural applications.
