Efficient Adaptive Rotated Object Detection for 1D and QR Barcodes
This study introduces EA-OBB, a lightweight rotated object detection framework designed for detecting one-dimensional (1D) and Quick Response (QR) barcodes. Built upon the YOLO11 architecture, EA-OBB integrates several innovative modules—KWConv, ORPNCSPELAN, and LADH-OBB—to enhance both accuracy and computational efficiency in rotated object detection. The KWConv module utilizes a dynamic convolution kernel mechanism to improve rotational barcode feature extraction. The ORPNCSPELAN module enhances computational efficiency through multi-path feature aggregation and online re-parameterization. The LADH-OBB module decouples classification and regression tasks, improving the precision of rotation angle regression. To further adapt to resource-constrained environments, this study incorporates the Taylor Pruning algorithm, significantly reducing model parameters and computational costs. Experimental results on the RotBar dataset demonstrate the superior performance of EA-OBB, achieving an optimal balance of precision, recall, and computational complexity compared to existing methods.
Executive Impact: Revolutionizing Barcode Logistics

EA-OBB Foundation: YOLO11 Enhancements
The EA-OBB model is built upon the YOLO11 architecture, specifically enhanced for rotated object detection. It integrates KWConv for dynamic feature extraction, ORPNCSPELAN for efficient multi-path feature aggregation with online re-parameterization, and LADH-OBB for decoupled classification and regression tasks, including rotation angle prediction. This architecture aims to optimize performance for barcodes, which exhibit high aspect ratios and arbitrary orientations. The integration of Taylor Pruning further reduces computational complexity and storage requirements.
Breakthrough Modules for Rotated Barcode Detection
KWConv Module: Utilizes a dynamic convolution kernel mechanism that adaptively adjusts weights based on input features, improving feature extraction for rotated and line-based barcode structures.
ORPNCSPELAN Module: An optimized version of RepNCSPELAN from YOLOv9, combining OREPA's online re-parameterization with GELAN's multi-path feature flow. It enhances computational efficiency during inference by compressing complex paths into single kernels.
LADH-OBB Module: Decouples classification and regression tasks with an asymmetric design. It includes a specialized rotation angle regression branch using depthwise separable convolution and distributional focal loss, boosting precision for rotated objects.
Taylor Pruning: An algorithm for model compression that estimates parameter importance based on loss function impact, effectively reducing model parameters and GFLOPs while maintaining high accuracy.
Unmatched Efficiency and Accuracy in Diverse Conditions
Experimental results on the RotBar dataset demonstrate EA-OBB's superior performance, achieving an optimal balance of precision, recall, and computational complexity compared to existing methods. It achieves high mAP@0.5 scores (e.g., 88.7% on validation) with significantly fewer parameters (1.3M) and lower GFLOPs (1.3G), leading to inference latencies as low as 0.9ms. This makes EA-OBB exceptionally suitable for real-time, resource-constrained embedded applications, handling complex backgrounds, lighting variations, blur, and partial occlusions effectively.
