In this survey, we offer a thorough overview of existing approaches to nucleus instance segmentation, exploring both traditional and deep learning-based methods. Traditional methods include watershed, thresholding, active contour model, and clustering algorithms, while deep learning methods include one-stage methods and two-stage methods. For these methods, we examine their principles, procedural steps, strengths, and limitations, offering guidance on selecting appropriate techniques for different types of data. Furthermore, we comprehensively investigate the formidable challenges encountered in the field, including ethical implications, robustness under varying imaging conditions, computational constraints, and the scarcity of annotated data.

Conventional methods, which frequently rely on predefined rules and filters, are inadequate for managing intricate noise patterns while maintaining image features. In order to tackle the issue of real-world image denoising, we investigate and integrate a new novel technique named recursive context fusion network (RCFNet) employing a deep convolutional neural network, demonstrating superior performance compared to current state-of-the-art approaches. RCFNet consists of a coarse feature extraction module and a reconstruction unit, where the former provides a broad contextual understanding and the latter refines the denoising output by preserving spatial and contextual details. Deep CNN learns features instead of using conventional methods, allowing us to improve and refine images. Dual attention units (DUs), in conjunction with the multi-scale resizing Block (MSRB) and selective kernel feature fusion (SKFF), are incorporated into the network to ensure efficient and reliable feature extraction. To demonstrate the advantages and challenges of combining many configurations into a single pipeline, we take a more detailed look at the results. By leveraging the complementary properties of these networks and computational models, we prefer to contribute to the creation of techniques that enhance image restoration while preserving crucial information, therefore encouraging further research and applications in image processing and artificial intelligence. The RCFNet achieves a high structural similarity index (SSIM) of 0.98 and a peak signal-to-noise ratio (PSNR) of 43.4 dB, outperforming many state-of-the-art methods on two benchmark datasets (DND and SIDD) and demonstrating its superior real-world image denoising ability.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70143","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144519804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While recent advances in image generation and virtual try-on technologies have introduced partial automation, existing methods still lack controllability and struggle to maintain semantic consistency in garment pose and structure, restricting their applicability in real-world design scenarios. In this work, we present CG-VTON, a controllable virtual try-on framework designed to generate high-quality try-on images directly from clothing design sketches. The model integrates multi-modal conditional inputs, including dense human pose maps and textual garment descriptions, to guide the generation process. A novel pose constraint module is introduced to enhance garment-body alignment, while a structured diffusion-based pipeline performs progressive generation through latent denoising and global-context refinement. Extensive experiments conducted on benchmark datasets demonstrate that CG-VTON significantly outperforms existing state-of-the-art methods in terms of visual quality, pose consistency, and computational efficiency. By enabling high-fidelity and controllable try-on results from abstract sketches, CG-VTON offers a practical and robust solution for bridging the gap between conceptual design and realistic garment visualization.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70144","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, traditional algorithms and deep learning models still face challenges in small and unevenly distributed object detection tasks. To address this problem, we propose the MCD-YOLOv10n model by introducing the MEMAttention module, which combines EMAttention with multiscale convolution, uses Softmax and AdaptiveAvgPool2d to adaptively compute feature weights, dynamically adjusts the region of interest, and captures cross-scale features. In addition, the C2f_MEMAttention and C2f_DSConv modules are formed by the fusion of C2f with MEMAttention and DSConv, which enhances the model's ability of extracting and adapting to irregular target features. Experiments on three datasets, VisDrone-DET2019, Exdark and DOTA-v1.5, show that the evaluation metric mAP50 achieves the best detection accuracy of 32.9%, 52.9% and 68.2% when the number of holdout parameters is at the minimum value of 2.24M. Moreover, the mAP50-95 metrics (19.5% for VisDrone-DET2019 and 45.0% for DOTA-v1.5) are 1.1 and 1.2 percentage points ahead of the second place, respectively. In terms of Recall, the VisDrone-DET2019 and DOTA-v1.5 datasets improved by 1.0% and 0.7% over the baseline model. These results validate that MCD-YOLOv10n has strong adaptability and generalization ability for small object detection in complex scenes.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70145","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the recognition of swimming postures is considered as an important section the coaches implement training plans. Usually, the recognition of swimming postures is achieved through coach observation; however, this approach is inefficient and lacks sufficient accuracy. To address this issue, a novel recognition method is proposed. In the proposed method, different swimming postures are assigned a different score via using a two-stage scoring mechanism. The feature regions of swimming postures can be accurately identified. Following that, the assigned score is put into the Softmax layer of the proposed convolutional neural networks. Finally, 4000 images including six swimming postures are used as an experimental set. The experimental results show that the proposed method achieves 92.73% testing accuracy and 89.03% validation accuracy in the recognition of the six swimming postures, defeating against the opponents. Meanwhile, our method outperforms some competitors in terms of training efficiency. The proposed two-stage scoring mechanism can be used for image recognition in large-scale scenarios. Moreover, the two-stage scoring mechanism is independently of specific scenarios in process of assigning a score value for feature regions of images. Not only that, the two-stage scoring mechanism can replace complex network structures, so as to reduce the work of training parameters.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70140","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also fuse the features with rich details from the upper encoder during the up-sampling process to reduce the loss of feature information.

Low-light image enhancement methods focus on solving the problem of brightness in dark areas while eliminating the degradation of low-light images. To solve the above problems, we proposed a hybrid CNN-transformer multi information fusion network (HCTMIF) for low-light image enhancement. In this paper, the proposed network architecture is divided into three stages to progressively improve the degraded features of low-light images using the divide-and-conquer principle. First, both the first stage and the second stage adopt the encoder–decoder architecture composed of transformer and CNN to improve the long-distance modeling and local feature extraction capabilities of the network. We add a visual enhancement module (VEM) to the encoding block to further strengthen the network's ability to learn global and local information. In addition, the multi-information fusion block (MIFB) is used to complement the feature maps corresponding to the same scale of the coding block and decoding block of each layer. Second, to improve the mobility of useful information across stages, we designed the self-supervised module (SSM) to readjust the weight parameters to enhance the characterization of local features. Finally, to retain the spatial details of the enhanced images more precisely, we design the detail supplement unit (DSU) to enrich the saturation of the enhanced images. After qualitative and quantitative analyses on multiple benchmark datasets, our method outperforms other methods in terms of visual effects and metric scores.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70127","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing methods predict the homography matrix either indirectly by evaluating the 4-key-point coordinate deviation in paired images with the same visual content or directly by fine-tuning the 8 degrees of freedom numerical values that define the matrix. However, these approaches often fail to effectively incorporate coordinate positional information and overlook optimal application scenarios, leading to significant accuracy bottlenecks, particularly for paired images with differing visual content. To address these issues, we propose an approach that integrates both methods in a staged manner, leveraging their respective advantages. In the first stage, positional information is embedded to enhance convolutional computations, replacing serial concatenation in traditional feature fusion with parallel concatenation, while using 4-key-point coordinate deviation to predict the macroscopic homography matrix. In the second stage, positional information is further integrated into the input images to refine the direct 8 degrees of freedom numerical predictions, improving matrix fine-tuning accuracy. Comparative experiments with state-of-the-art methods demonstrate that our approach achieves superior performance, yielding a root mean square error as low as 1.25 and an average corner errror as low as 14.1 in homography transformation of competitive sports image pairs.","PeriodicalId":56303,"journal":{"name":"IET Image Processing","volume":"19 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/ipr2.70136","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144473143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
