Abstract

For mobile devices, recognizing plant leaves in real time is an important task. But traditional convolutional neural networks are not good at this task. They struggle to work fast enough on these devices. To fix this problem, this paper looks into optimization methods for lightweight convolutional neural networks. The paper picks three baseline models: MobileNetV2, ShuffleNetV2, and EfficientNet-B0. It also uses several compression techniques, such as knowledge distillation, pruning, and quantization. Along with structural improvements, these methods help build lighter models. The paper tests these models on the Flavia dataset. The results are clear. The optimized model reaches a Top-1 accuracy of 97.51%. Its parameter count drops to 1.4M. The model size is reduced by 75%. And its inference speed becomes much faster, which meets the needs of mobile devices.
