The cell nuclei in pathology images provide clinicians with important tissue information for diagnosis. However, nucleus segmentation faces various challenges such as image blurring, blurred boundaries, noise, and holes. Existing methods are difficult to achieve the expected results field of nuclei. Based on this, this study proposes a framework based deblurring region proxies (DRPVit) medical decision-making systems. First, we employ an information-enhanced iterative filtering adaptive network (IE-IFANet) improve clarity regions boundaries. Then, considering performance complexity network, RegProxy model is used segmentation. utilizes agent represent homogeneous semantics, transformer encoder relationship between these regions, finally classifier prediction. Finally, introduce combined loss function consisting boundary tversky balance optimize edges regions.

Abstract Due to the improvement in computing power and development of computer technology, deep learning has pene‐trated into various fields medical industry. Segmenting lesion areas scans can help clinicians make accurate diagnoses. In particular, convolutional neural networks (CNNs) are a dominant tool vision tasks. They accurately locate classify areas. However, due their inherent inductive bias, CNNs may lack an understanding long‐term dependencies images, leading less grasping details images. To address this problem, we explored Transformer‐based solution studied its feasibility imaging tasks (OstT). First, performed super‐resolution reconstruction on original MRI image osteosarcoma improved texture features tissue structure reduce error caused by unclear during model training. Then, propose method for segmentation. A gated axial attention is used, which augments existing architectures introducing additional control mechanism self‐attention module improve segmentation accuracy. Experiments real datasets show that our outper‐forms models such as Unet. It effectively assist doctors examinations.

Abstract Malignant tumors are a common cytopathologic disease. Pathological tissue examination is key tool for diagnosing malignant tumors. Doctors need to manually analyze the images of pathological sections, which not only time-consuming but also highly subjective, easily leading misdiagnosis. Most existing computer-aided diagnostic techniques focus too much on accuracy when processing images, and do take into account problems insufficient resources in developing countries meet training large models difficulty obtaining medical annotation data. Based this, this study proposes an artificial intelligence multiprocessing scheme (MSPInet) digital pathology We use such as data expansion noise reduction enhance dataset. Then we design coarse segmentation method cell nuclei based Transformer Semantic Segmentation further optimize tumor edges using conditional random fields.
