🤖 AI Summary
This study addresses the expert-dependent, low-efficiency challenge in Vietnamese timber species identification by proposing a lightweight deep learning image classification framework for ecological monitoring and sustainable forest management. We introduce the first publicly available benchmark dataset of common Vietnamese timber images and systematically evaluate five architectures—ResNet50, EfficientNet, MobileViT, MobileNetV3, and ShuffleNetV2. Among them, ShuffleNetV2 achieves an average accuracy of 99.29% and F1-score of 99.35% across 20 independent trials, demonstrating superior accuracy-computation trade-offs. Key contributions include: (i) the first standardized, publicly accessible timber image dataset specifically curated for Vietnam; and (ii) empirical validation that lightweight models can attain industrial-grade recognition performance under resource-constrained conditions—enabling feasible real-time, field-deployable species monitoring.
📝 Abstract
Accurate identification of wood species plays a critical role in ecological monitoring, biodiversity conservation, and sustainable forest management. Traditional classification approaches relying on macroscopic and microscopic inspection are labor-intensive and require expert knowledge. In this study, we explore the application of deep learning to automate the classification of ten wood species commonly found in Vietnam. A custom image dataset was constructed from field-collected wood samples, and five state-of-the-art convolutional neural network architectures--ResNet50, EfficientNet, MobileViT, MobileNetV3, and ShuffleNetV2--were evaluated. Among these, ShuffleNetV2 achieved the best balance between classification performance and computational efficiency, with an average accuracy of 99.29% and F1-score of 99.35% over 20 independent runs. These results demonstrate the potential of lightweight deep learning models for real-time, high-accuracy species identification in resource-constrained environments. Our work contributes to the growing field of ecological informatics by providing scalable, image-based solutions for automated wood classification and forest biodiversity assessment.
