Extracting insights from filters and feature maps

• Classification of leaf images such as Hypersensitive response (HR), normal, mosaic virus
• Visualization of filters and feature maps in leaf disease image classifiers
• In this way, we can visually identify which features have a significant impact on classification, and further extract the visual characteristics of the three kinds of leaf states.
