GIWT-YOLO: an efficient multi-scale framework for real-time Scolytinae pests detection
September 2025 • Jingwei Liu, Yongke Li, Lei Wang, Yunjie Zhao, Bowen Mao, Pengying Wang
The broad range of Scolytinae pests sizes and their subtle visual similarities, especially in smaller species, continue to challenge the accuracy of mainstream object detection models. To address these challenges, this paper proposes GIWT-YOLO, a lightweight detection model based on YOLOv11s, specifically tailored for Scolytinae pests detection. (1) We designed a lightweight multi-scale convolution module, GIConv, to improve the model’s ability to extract features at different pest scales. This module enhances the…
