YOLOv11 Algorithm Overview
YOLOv11, the latest in the YOLO series, represents a significant evolution in object detection, designed for balancing accuracy and efficiency. Its architecture features a four-stage design: input preprocessing, backbone feature extraction, neck feature fusion, and head prediction output. Key innovations include the C3k2 module for optimized cross-layer connections and reduced complexity, the SPPF module for expanded receptive fields, and the C2PSA module for intelligent spatial attention, enhancing focus on key regions while suppressing background noise. This robust framework is highly adaptable, with five model configurations (N, S, M, L, X) to suit various deployment environments, from edge devices to high-end servers.
ADown Lightweight Downsampling Module
The ADown module is introduced to address the computational complexity in high-resolution remote sensing images. It employs a diversified downsampling strategy, integrating average pooling, max pooling, and convolution operations. This adaptive feature extraction, guided by learnable parameters, ensures that important feature information, especially for small targets and unclear boundaries, is preserved during dimension reduction. The module’s channel balancing mechanism further maintains the richness of feature representation, making it highly efficient without sacrificing detection accuracy. ADown's plug-and-play design allows seamless integration into the YOLOv11 network, significantly reducing GFLOPs.
DySample Dynamic Upsampling Module
The DySample module is a crucial innovation for accurate feature restoration and localization in remote sensing images. Unlike traditional fixed sampling methods, DySample dynamically learns optimal sampling positions based on input feature content, significantly enhancing the preservation of geometric features and boundary information. It consists of an input feature map processing unit, a sampling point generator, and a dynamic sampling result aggregator. This adaptive strategy is particularly effective for targets with varying shapes, scales, and orientations, ensuring higher quality feature restoration and improving detection performance, especially for small targets and complex boundaries.
Experimental Validation and Results
Experiments on the NWPU VHR-10 dataset confirm the effectiveness of the improved YOLOv11. Compared to the baseline, the optimized algorithm achieves a 1.6 percentage point increase in mAP50 (from 0.835 to 0.851), while simultaneously reducing computational complexity from 6.3 GFLOPs to 5.7 GFLOPs (a 9.5% reduction). The ablation study demonstrated the individual and synergistic benefits of ADown (reducing GFLOPs with a minor accuracy trade-off) and DySample (enhancing mAP50 with a slight GFLOPs increase), highlighting their combined power to achieve optimal balance.
