Thus, we propose a domain-guided multi-frequency underwater image enhancement network (DGMF), which generate high quality images by learning water-type-related features and capturing multi-frequency information. Specifically, we introduce a domain-aware module equipped with a water type classifier, which can distinguish the impacts of different water types, and guide the update of the model towards the specific domain. In addition, we design a multi-frequency mixer that couples Multi-Group Convolution (MGC) and Global Sparse Attention (GSA) to more effectively captures local and global information.

In distributed machine learning environments however, individual AI agents are merely part of a system where decisions are made in a centralized and aggregated fashion or require a fixed network topology, a practice prone to security risks and collaboration is nearly absent. For instance, Byzantine Failures may tamper both the training and inference stage of individual AI agents, leading to significantly reduced overall system performance. Inspired by societal practices, we propose a decentralized inference strategy where each individual agent is empowered to make their own decisions, by exchanging and aggregating information with other agents in their network. To this end, a “Quality of Inference” consensus protocol (QoI) is proposed, forming a single commonly accepted inference rule applied by every individual agent. The overall system knowledge and decisions on specific manners can thereby be stored by all individual agents in a decentralized fashion, employing e.g., blockchain technology. Our experiments in classification tasks indicate that the proposed approach forms a secure decentralized inference framework, that prevents adversaries at tampering the overall process and achieves comparable performance with centralized decision aggregation methods.</div></div>","PeriodicalId":49521,"journal":{"name":"Signal Processing-Image Communication","volume":"136 ","pages":"Article 117306"},"PeriodicalIF":3.4,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143643817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, deep feature-based correlation filters are affected by undesired boundary effects, which reduce the tracking performance. Moreover, the tracker moves towards a region that is identical to the target due to the sudden variation in target appearance and complicated background areas. To overcome these issues, we propose an adaptive spatially regularized target attribute-aware background suppressed deep correlation filter (ASTABSCF). To do this, a novel adaptive spatially regularized technique is presented, which aims to learn an efficient spatial weight for a particular object and fast target appearance variations. Specifically, we present a target-aware background suppression method with dual regression approach, which utilizes a saliency detection technique to produce the target mask. In this technique, we employ the global and target features to get the dual filters known as the global and target filters. Accordingly, global and target response maps are produced by dual filters, which are integrated into the detection stage to optimize the target response. In addition, a novel adaptive attribute-aware approach is presented to emphasize channel-specific discriminative features, which implements a post-processing technique on the observed spatial patterns to reduce the influence of less prominent channels. Therefore, the learned adaptive spatial attention patterns significantly reduce the irrelevant information of multi-channel features and improve the tracker performance. Finally, we demonstrate the efficiency of the ASTABSCF approach against existing modern trackers using the OTB-2013, OTB-2015, TempleColor-128, UAV-123, LaSOT, and GOT-10K benchmark datasets.</div></div>","PeriodicalId":49521,"journal":{"name":"Signal Processing-Image Communication","volume":"136 ","pages":"Article 117305"},"PeriodicalIF":3.4,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143686523","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper examines the impact of light field compression on the performance of subsequent computer vision tasks.

By leveraging a diverse dataset of light field images, we thoroughly evaluate the performance of various face recognition algorithms when subjected to different conventional and learning-based compression techniques, such as JPEG Pleno, ALVC, and SADN-QVRF. Our findings reveal a noticeable decline in peak recognition performance as compression levels increase, given specific recognition frameworks. Furthermore, we identify a significant shift in the recognition threshold, particularly in response to higher degrees of compression. Secondly, by relying on a novel disparity estimation algorithm, we explore the loss of information across light field perspectives. Our results highlight a disconnect between the preservation of visual fidelity and the loss of minute detail crucial for the preservation of disparity information in light field images.

Therefore, accurately predicting the quality of underwater images is crucial. To tackle this issue, this study introduces a novel Underwater Image Quality Assessment method that combines visual and structural information. First, the CIELab map, gradient feature map, and Mean Subtracted Contrast Normalized feature map of the underwater image are obtained. Then, these feature maps are divided into non-overlapping 32x32 patches, and each patch is fed into the corresponding sub-network. This method allows for a comprehensive description of the changes in visual and structural information resulting from quality degradation in underwater images. Subsequently, the features extracted by the multipath network are fused using a feature fusion network to promote feature complementarity and overcome the limitations of individual features. Finally, the relationship between underwater image quality and fusion features was learned to obtain an evaluation model. Furthermore, the quality of the underwater image can be measured by combining the quality prediction scores of different patches. Experimental results on underwater image datasets demonstrate that the proposed method can achieve more accurate and stable quality measurement results with a more lightweight structure.

This capability enhances the understanding of the overall structure and details of the image during the denoising process. However, the computational complexity of global self-attention increases quadratically with higher spatial resolutions, making it unsuitable for the real-time denoising of high-resolution and high-noise images. And, the use of local windows alone neglects the long-range pixel correlations. Furthermore, the self-attention mechanism applies a global weighting to the pixels of the input image, which can lead to the smoothing or loss of fine details. To enrich structural information and alleviate the computational complexity associated with global self-attention, we propose an edge-enhanced windowed multi-head self-attention mechanism (EWMSA). This mechanism combines edge enhancement with windowed self-attention to reduce computational demands while allowing edge features to better preserve detail and texture information. To mitigate the effects of ineffective features with low weights, we introduce a feed-forward network with a gate control strategy (LGFN). This network adjusts pixel weights to prioritize attention on effective pixels, thereby enhancing their prominence. Furthermore, to compensate for the limitations of window-based self-attention in global pixel utilization, we propose a deformable convolution block (DFCB). This block improves the interaction of contextual information and allows for better adaptation to texture variations within the image.
