However, the complex issue of multiphase segmentation in micro-CT images significantly hinders the effective advancement of subsequent research. Traditional segmentation methods require manual labor, which is not only time-consuming and labor-intensive but also inherently prone to errors, failing to meet contemporary industrial demands for high precision and efficiency. Therefore, achieving efficient and accurate segmentation of these complex micro-tomography images, particularly multiphase segmentation, is an urgent priority. To rapidly and accurately analyze the microstructure and mineral composition of steel slag, this paper proposes an improved U-Net-based steel slag image segmentation method utilizing deep learning algorithms. Using steel slag micrographs as the dataset, we innovatively employ a VCU-Net model based on high-level semantic feature extraction and a dual attention mechanism for segmentation training. Through rigorous experimental validation and analysis, the improved U-Net model achieves 3.16 and 3.61% improvements in mean intersection over union (MIoU) and mean pixel accuracy (MPA), respectively. Compared to PSPNet, Deeplabv3+, DDR-U-Net, and Swin-U-Net, the enhanced U-Net model achieves finer texture feature capture, demonstrates superior adaptability to complex mineral textures, and enables more precise identification of mineral boundary features, thereby improving the accuracy and efficiency of steel slag mineral recognition.</p>","PeriodicalId":55411,"journal":{"name":"Automation and Remote Control","volume":"86 9-12","pages":"349 - 361"},"PeriodicalIF":0.6,"publicationDate":"2026-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147738921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traffic prediction, a core component of ITS is quite important in improving traffic management, enhancing public safety, and promoting sustainable urban mobility. However, deep learning models’ efficacy in traffic prediction is heavily reliant on the quality of input data. Data noise, biases, and missing values can significantly hinder model accuracy by introducing spurious correlations that do not reflect true causal relationships. Additionally, imbalanced training data can skew the model’s learning process, leading to suboptimal performance and reduced generalization. Traditional feature selection methods often find it difficult to depict intricate, nonlinear interactions in high-dimensional datasets, further complicating the task. To overcome these obstacles, this research proposes a novel graph-GRU temporal fusion network (GGTFN) that combines graph neural networks (GNNs) and gated recurrent units (GRUs) to capture both spatial and temporal dependencies in traffic data. The model also incorporates regression-based imputation during preprocessing to handle missing data and uses SMOTE-NC to address class imbalance. Experimental findings indicate that the GGTFN performs better than other previous techniques, achieving the lowest RMSE values for short- to medium-term traffic predictions (15–30 min). Although performance decreases for longer prediction horizons, the proposed model demonstrates robustness and effective generalization across diverse traffic conditions.
