However, most existing studies restrict vision-language interactions in pair-wise correlations and only employ full-parameter fine-tuning under a single fusion scheme, leading to semantic inconsistency and potentiality ignorance of pre-trained medical vision-language models. In this paper, we introduce a parameter-efficient multimodal hypergraph adapter based model under a hybrid fusion paradigm of bidirectional early-fusion and late-fusion. Specifically, the multimodal hypergraph adapter is proposed to enhance interactions between several stages (blocks) of the vision and language encoders in medical CLIP models, which exploits high-order correlations by treating visual features as nodes and textual features as hyperedges, and propagates complementary information to refine features concurrently through hypergraph message passing. Additionally, we explore the hybrid utilization of word- and sentence-level textual features for fine-grained alignments in the task-specific decoder. Furthermore, two training strategies are employed for encoders from medical CLIP models: keeping the language encoder frozen only, or keeping both encoders frozen as parameter-efficient fine-tuning (PEFT) to fully exploit prior knowledge in the pre-trained model via adapters. Our experimental evaluations on the QaTa-COV19, CheXlocalize and MosMedData+ datasets demonstrate that our method significantly surpasses existing approaches, highlighting its superiority and effectiveness for text-driven medical image segmentation.</div></div>","PeriodicalId":50570,"journal":{"name":"Displays","volume":"92 ","pages":"Article 103330"},"PeriodicalIF":3.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145883474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve diagnostic accuracy, multi-threshold image segmentation (MTIS) techniques based on metaheuristic (MH) algorithms are widely adopted. However, traditional MH algorithms often suffer from premature convergence, limiting their global search capabilities. This study proposes a Quantum-Enhanced Hybrid Gold Rush Optimizer (QHGRO) that integrates quantum computing to enhance optimization performance. QHGRO is applied to an MTIS framework that utilizes a non-local means two-dimensional histogram to encode image information and employs Rényi entropy as the fitness function. The optimizer incorporates a Quantum Computing-Driven Adaptive Variation strategy, where quantum superposition enables parallel exploration of multiple states, and quantum mutation introduces controlled randomness to enhance global search and avoid local optima. To further improve performance, QHGRO includes a Stochastic Lévy Flight strategy during the Collaboration between Prospectors phase to enhance exploration and population diversity, and a Dynamic Fitness Distance Balance strategy during the Gold Mining phase to improve convergence accuracy. Experimental results on CEC2017 and CEC2022 benchmark functions demonstrate that QHGRO achieves competitive performance, often approaching global optima. In two engineering design problems—Speed Reducer Design and Three-Bar Truss Design—QHGRO outperforms classical algorithms (PSO, GWO, DE), newer algorithms (NRBO, CPO, RUN, BKA, SBOA, GRO), and advanced variants (MPSO, IAGWO).

To address this issue, we propose a joint degradation model grounded in the visible-light imaging process, which unifies motion blur and low sampling frequency degradation to characterize the linear relationship between features of deblurring and super-resolution. Guided by this model, we propose a novel Task-Aware Feature Coupling Network (TAFCNet) to enable restoration of local non-uniformly blurred regions and accurate reconstruction of structurally consistent content. Specifically, our method employs Stacked Nonlinear Feature Separator (SNFS) branch to enhance the representation of local information, and a High-Low Frequency Feature Mixer (HLFFM) branch operating in the frequency domain to obtain texture features from low-resolution images. To adaptively couple dual-task features, we further propose a Task-Aware Gating (TAG) module to mitigate feature conflicts.
