Despite remarkable progress in recent years, it is still challenging for predictive models to learn robust representations avoiding blurry objects, due to several aspects. (i) <em>Incomplete semantic structures.</em> Spatial structures including textures, positions and shapes of potential semantics are not comprehensively modeled, where existing methods directly learn from raw pixels or limited structural features within specific categories. (ii) <em>Absent structural correlation.</em> Correlations between images are commonly modeled by recurrent and convolutional architectures in this direction, while leaving correlations among explicit structures lack of explorations. (iii) <em>Non-selective structural fusion</em>. Existing fusion of structures in this task focuses on the concatenation of data or intermediate features, resulting features being equally treated and representative ones are ignored. In order to address above problems, we propose a spatiotemporal semantic structural representation learning pipeline in this study. (i) For comprehensively spatial structural modeling, this pipeline starts by SAM-based segmenting potential semantic objects, then providing spatial structures including textures, positions and shapes. (ii) To realize structural correlation modeling, temporal self-attention modules are exploited in this pipeline to extract compressed temporal features in corresponding structures. (iii) Finally for fusion of structural features, spatiotemporal semantic structural representations are accessed by integrating compressed features through cross-attention based fusion modules. Extensive experiments are conducted on both KITTI, KTH and Sthv2 datasets, showing superior performance of our model and especially better visual quality of semantic parts.</div></div>","PeriodicalId":19268,"journal":{"name":"Neurocomputing","volume":"637 ","pages":"Article 130159"},"PeriodicalIF":5.5,"publicationDate":"2025-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739936","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing strategies employ a unified learning paradigm to integrate multiple features, and they lead to the neglect of critical local patterns and intricate relationships among features. Furthermore, most of models are generally designed to be complex and difficult to leverage and interpret in practical applications. To address these issues, FCAnet, a novel generic cross-attention-based feature fusion approach is prpopsed. FCAnet views the embedding space of multiple features as interactive patterns and utilizes cross-attention mechanisms to analyze both spatial correlations and discrepancy information simultaneously. Specifically, a dual-branch feature extraction module (DBFE) is first designed to effectively capture the 3D differential entropy (DE) and 3D power spectral density (PSD) feature maps of EEG. Secondly, a cross-attention feature fusion network (CAFFN) integrates a designed discrepancy information injection block (DIIB) with a common information injection block (CIIB) unit, facilitating significant interaction between different features. Finally, a time augmentation block (TAB) is employed to recover information lost from high-level representations, reusing discriminative temporal feature maps.

However, these approaches fail to fully exploit the inherent tree structure of such sequences. To address these limitations and leverage established data properties, we propose Formation Tree-CLIP (FT-CLIP). FT-CLIP utilizes formation trees to represent characters and incorporates a dedicated tree encoder, significantly improving performance in both seen and unseen character recognition tasks. We further introduce masking for both character images and tree nodes, enabling efficient and effective training.

The existing main methods using CNN-based models and transformer-based models aimed at removing lens flare, however, perform poorly in removing large-scale flares because they lack the inductive bias for spatial equivariance and the ability to capture both global and local features simultaneously. This deficiency prevents networks from quickly pinpointing the locations of flares and from fully learning the contextual content necessary for repairing contaminated areas, and they also struggle with restoring uncontaminated regions. In this paper, we introduce the Mask-Q Attention Network, a multi-scale framework designed to address the flare removal problem. Our approach focuses on extracting both global and local features, leveraging ResBlock for local feature extraction and Mask-Q Attention for capturing global features. In the Mask-Q Attention, we enhance the localization capability of the attention mechanism by integrating the flare mask with the query vector (Q) in the self-attention process. The flare mask is obtained by binarizing the initial image. This integration with the flare mask effectively resolves the issue of the lack of spatial equivariance in Transformer blocks, providing the network with prior knowledge of the flare locations.

In this paper, Enhanced Inter-Camera Person Re-identification leveraging Mixed-Order Relation-Aware Recurrent Neural Network (EICPR-MORRNN-TTAO) is proposed. The input images are collected from Market-1501, MSMT17, and Duke MTMC-reID datasets. Afterward, the input image is supplied to pre-processing.
