Mobile Leaf Identification System using CNN applied to plants in Hokkaido

The ability to identify plant types is important when conducting vegetation surveys. This ability requires investigators experience. We propose a mobile application using convolutional neural networks (CNNs) that will help beginners identify plant species. We compare three CNN models, VGG19, MobileNet, and MobileNetV2. Our plant identification application using MobileNetV2 shows an average F1 score of 0.992, indicating its high performance and practicality. The implemented system shows a practical performance of 338.1 ms per picture on a tablet-type device.
