Improving Accuracy of Corn Leaf Disease Recognition Through Image Enhancement Techniques
Corn leaf disease recognition represents a critical challenge in modern agricultural systems, where early detection can significantly impact crop yield and food security. This research investigates the application of advanced image enhancement techniques to improve the accuracy of automated corn leaf disease identification. The study implements a comprehensive preprocessing pipeline incorporating histogram equalization, contrast enhancement, and noise reduction algorithms to optimize image quality before feature extraction and classification. Experimental validation using a dataset of 3,000 corn leaf images demonstrates substantial accuracy improvements across multiple disease categories. The proposed enhancement framework achieves 94.7% recognition accuracy, representing a 12.3% improvement over baseline methods without preprocessing. Statistical analysis confirms the significance of image enhancement in reducing misclassification rates, particularly for early-stage disease symptoms. The methodology provides a practical solution for agricultural automation systems, enabling more reliable disease detection in field conditions with varying lighting and environmental factors.
