Abstract:

The quality evaluation of defect data synthesized through data augmentation can facilitate high-quality expansion of defect data, thereby mitigating the problem of poor detection model performance caused by insufficient defect data. When evaluating the quality of synthetic defect data, existing quality evaluation algorithms primarily focus on the distortion characteristics of the data but tend to overlook the defect attributes of the data. To address this issue, a SDENet model based on attention feature enhancement (AFE) and multi-scale attention quality perception (MAQP) was proposed, which comprehensively considered the distortion characteristics and defect attributes of synthesized defect data for quality evaluation. Firstly, the AFE module improved the model's generalization ability to defects of different sizes and positions through dual-branch pooling operation, while also using an attention mechanism to enhance the feature expression ability of the model. Secondly, the MAQP module vectorized and fused the features enhanced by AFE to better perceive the quality of synthetic defect data. Finally, the fused features were fed into the quality evaluation section, and the final evaluation score was generated. Experiments conducted on the constructed synthetic defect data set of road cracks demonstrated that the SDENet model achieved optimal results in RMSE, RMAE, PLCC, and SROCC metrics, with improvements of 10.7%, 5.0%, 1.8% and 1.8% compared to the suboptimal model, thereby verifying the effectiveness of the model. On the distorted dataset TID2013, the SDENet model also produced competitive results, reaching 0.902 and 0.876 on the PLCC and SROCC metrics, respectively.
