Currently, limited literature addresses this issue. To tackle this challenge, we propose a prior embedding-driven architecture for long-distance blind iris recognition. Our approach introduces a blind iris image restoration network named Iris-PPRGAN. To effectively restore the texture of blind iris images, Iris-PPRGAN incorporates a Generative Adversarial Network (GAN) as a Prior Decoder and a Deep Neural Network (DNN) as the encoder. To enhance iris feature extraction, we also developed a robust iris classifier by modifying the bottleneck module of InsightFace, referred to as Insight-Iris. Initially, a low-quality blind iris image is restored using Iris-PPRGAN, and the restored image is subsequently recognized through Insight-Iris. Experimental results on the public CASIA-Iris-distance dataset demonstrate that our method outperforms state-of-the-art blind iris restoration techniques. Specifically, the recognition rate for long-distance blind iris images improves from 80.77 % (without restoration) to 90.38 % after applying our method, reflecting an approximate ten-percentage-point improvement. These results, validated both quantitatively and qualitatively, underscore the effectiveness of our approach in addressing the challenges of long-distance blind iris recognition.</div></div>","PeriodicalId":55362,"journal":{"name":"Biomedical Signal Processing and Control","volume":"109 ","pages":"Article 108048"},"PeriodicalIF":4.9,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143936295","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Deep learning (DL) algorithms benefit significantly from extensive and diverse datasets during training, but obtaining a sufficient amount of labeled data for macular edema is challenging. An insufficient dataset may result in overfitting, reducing the network’s capability to generalize the diverse cases. An optical coherence tomography (OCT) framework is utilized to solve the problem of diabetic macular edema (DME). Due to the complex nature of this condition and the saturation of healthcare in affluent nations, it is among the main factors that induce blindness. In this paper, a novel DIO-RegNet was introduced for the early recognition of the ME using DL techniques. The input OCT images are pre-processed by a Gaussian adaptive bilateral filter to enhance the image quality. The noise-free images are fed to the Modified DeepLabV3 + to segment the Macular area in retinal images. Then, the segmented Macular region is fed into deep learning-based RegNet for extracting the structural feature. Finally, the Dingo Optimization (DIO) algorithm is applied for the feature selection and classify the cases of macular edema.

Numerous studies in motor control have established that the central nervous system synchronizes muscle activation by sending a common drive to synergistic muscles, measurable through intermuscular coherence – the frequency correlation between two EMG signals. As interest grows in understanding how muscles synchronize during movement coordination, leveraging intermuscular coherence into musculoskeletal models represents an innovative approach. This could enhance the accuracy of muscle effort estimation and introduce a physiologically meaningful component of motor control. In this study, we introduce a new method that decomposes EMG signals into common and independent components, informed by intermuscular coherence, and integrates them into an EMG-driven model to estimate muscle moments. Using data from twenty-four healthy subjects performing horizontal upper limb extensions, we estimated moments of the four main muscles actuating the elbow and compared these estimations with those from a traditional EMG-driven model informed by full-wave rectified signal envelopes. Our results demonstrate that incorporating intermuscular coherence significantly enhanced kinetic data tracking and improved the robustness of muscle moment estimations against variations in model parameters, addressing a major limitation of traditional EMG-driven models. Furthermore, antagonist muscle moments were more accurately represented, resulting in more realistic co-contraction index values.</div><div>By integrating neural control strategies via intermuscular coherence into musculoskeletal models, the proposed approach offers a more accurate representation of muscle coordination.

However, segmenting cardio-cerebrovascular structures from medical images is highly challenging due to factors such as thin or blurred vascular shapes, imbalanced vessel-to-background pixel distribution, and interference from imaging artifacts. These difficulties render manual or semi-manual segmentation methods time-consuming, labor-intensive, and prone to inter-observer variability. Consequently, there is an increasing demand for automated segmentation algorithms. This paper presents the first comprehensive survey of deep learning techniques for cardio-cerebrovascular segmentation, covering supervised, semi-supervised, and unsupervised approaches for both cardiac and cerebral vasculature. We review state-of-the-art methods, including U-Net, Generative Adversarial Networks (GANs), Graph Convolutional Networks (GCNs), transformer models, diffusion models such as Denoising Diffusion Probabilistic Models (DDPM), foundation models like Segment Anything Model (SAM) and the SAM-VMNet models, as well as hybrid approaches combining multiple models with effective fusion techniques. We discuss the strengths and limitations of these methods, emphasizing their clinical applicability. Our analysis identifies key challenges, including the reliance on annotated data and the limitations of single-modality approaches, which fail to fully leverage the rich information available from multi-modal imaging sources. We highlight the importance of label-efficient, multi-modal deep learning as a promising direction for improving segmentation accuracy and robustness.

Clinicians vary in their treatment approaches for sleep hypopnea and sleep apnea, often regarding sleep apnea as more severe. However, most previous methods for detecting sleep-breathing events were binary classifications that merged hypopnea and apnea into a single category, which are inadequate for auxiliary diagnosis and accurate sleep quality monitoring today. In this study, we proposed a convolutional neural network (CNN) model called TriGNet, which aims to detect hypopnea and apnea events. TriGNet utilizes single-channel electrocardiogram (ECG) signals from the MIT-BIH polysomnography dataset to learn and differentiate between normal, hypopnea, and apnea events. We designed a 2D feature extraction component in the model, which processes 1D ECG signal data as 2D to obtain additional feature information. In addition, this study proposed a dynamic data regulation mechanism for capturing subtle variations among the three categories of ECG signals. The TriGNet model can directly learn features from ECG signals and effectively classify sleep-breathing events.
