An Edge Computing-Based Solution for Real-Time Leaf Disease Classification using Thermal Imaging
This addresses crop health monitoring for agriculture, but it is incremental as it applies existing deep learning methods with optimizations to a new dataset.
The paper tackles real-time leaf disease classification using thermal imaging on edge devices, achieving up to 2.13x faster inference times on resource-constrained hardware while maintaining state-of-the-art accuracy.
Deep learning (DL) technologies can transform agriculture by improving crop health monitoring and management, thus improving food safety. In this paper, we explore the potential of edge computing for real-time classification of leaf diseases using thermal imaging. We present a thermal image dataset for plant disease classification and evaluate deep learning models, including InceptionV3, MobileNetV1, MobileNetV2, and VGG-16, on resource-constrained devices like the Raspberry Pi 4B. Using pruning and quantization-aware training, these models achieve inference times up to 1.48x faster on Edge TPU Max for VGG16, and up to 2.13x faster with precision reduction on Intel NCS2 for MobileNetV1, compared to high-end GPUs like the RTX 3090, while maintaining state-of-the-art accuracy.
