Disease & Pest Detection (AI Analysis)
Overview
AI-driven disease and pest detection uses high-resolution drone imagery, multispectral data, and machine-learning algorithms to identify early signs of crop stress, infections, and pest infestations. By analyzing patterns such as discoloration, canopy texture changes, chlorophyll variations, and thermal anomalies, the system can detect issues long before they become visible to the human eye. This enables farmers to take rapid, targeted action—reducing crop losses, minimizing chemical usage, and improving overall field health. Automated alerts, geo-tagged reports, and severity mapping ensure precise interventions and significantly higher operational efficiency in modern precision agriculture.
Process Flow

Plant Disease Detection Using Computer Vision in Agriculture | ImageVision.ai
The workflow begins with collecting leaf images directly from the crop field, capturing samples of different plants such as potato, pepper, and tomato leaves showing disease symptoms. These images undergo preprocessing to enhance clarity by adjusting lighting, removing noise, and preparing them for analysis. After image acquisition, the cleaned dataset is stored and passed through data augmentation, where images are rotated, resized, and rescaled to increase dataset diversity and improve the model’s robustness. The augmented dataset is then split into two parts: a training dataset used to train the AI model and a testing dataset used to evaluate its accuracy. The AI model learns to recognize disease patterns during training, and once trained, it processes the testing data to detect leaf diseases automatically. Finally, performance analysis is carried out to measure how well the model identifies diseases, completing the full AI-powered disease detection pipeline
