By leveraging the uncertainty of the superposition state during the collapse, this method effectively preserves population diversity even with a very small population size. A smaller population size implies fewer calls to time-consuming simulations. Additionally, quantum entangled states are created for parts of an individual's gene, utilizing the characteristic that entangled states instantly affect each other upon collapse, to achieve parallel evolution of parts of the genes in multiple individuals. This parallel evolution significantly increases the search speed of the algorithm, thereby reducing the number of iterations. Fewer iterations also mean fewer calls to simulations.

It is very important in both military and civilian fields. Firstly, one low resolution image and three reference images are used as the input of VGG network to extract their feature maps at 4 × , 2 × , and 1 × scales. These feature maps at each scale are respectively blocked and used as a set of inputs in subsequent operations. Specifically, the low resolution features are divided into <span><math><msub><mrow><mi>N</mi></mrow><mrow><mi>i</mi></mrow></msub></math></span>blocks, and each block is further divided into <span><math><msub><mrow><mi>N</mi></mrow><mrow><mi>c</mi></mrow></msub></math></span>sub-feature-blocks.

The outputs of each layer are then iteratively mapped with the low-resolution features as inputs for next layers. Thus the final features include information from all the reference images and low-resolution image. Subsequently, an adaptive transfer module with multi-reference features and channel attention is used to match and transfer the information of each reference image, while achieving edge smoothing and noise filtering between different reference features. Finally, the quadruple super-resolution reconstruct result is got from the multi-scale feature fusion module and decoder.

However, existing methods often struggle with the complexity of lesion boundaries and the computational demands of Transformer-based approaches. To address these challenges, we propose a morphological difference and statistically sparse Transformer-based deep neural network for medical image segmentation, termed MD-SSFormer. It comprises two critical modules: the dual branch encoder (DBEncoder) module, and the morphological difference catcher (MDC). To extract abundant information at different aspects, a novel DBEncoder module integrates the capability of the convolutional neural network-based method in capturing local texture and the ability of the Transformer-based method in modeling global information. Compared to the conventional feature extraction methods, DBEncoder achieves comprehensive improvement. Furthermore, the statistics-based sparse Transformer (SSFormer) module develops an innovative statistical analysis and an adaptive patch-dividing strategy to perform attention-computing, which addresses the computational challenges associated with conventional Transformer-based models. Finally, considering the impacts of the blurry and complex boundaries, the MDC module employs the morphological operation and differential information extractor to refine the details, which achieves high-precision boundary understanding. Experimental results on five public datasets demonstrate MD-SSFormer's superior performance, achieving state-of-the-art Dice scores of 83.60 % on ISIC 2017, 79.52 % on Kvasir-SEG, 61.89 % on BUSI, 78.62 % on BraTS21, and 85.85 % on 3DIRCADb, outperforming other methods in accuracy, precision, and computational efficiency respectively.</div></div>","PeriodicalId":50737,"journal":{"name":"Applied Soft Computing","volume":"174 ","pages":"Article 113052"},"PeriodicalIF":7.2,"publicationDate":"2025-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the existing recognition methods are difficult to perform effective fault recognition when faced with inconsistent data distribution and unlabeled small sample data.
