Objectives Oral cavity-derived cancer pathological images (OPI) are crucial for diagnosing oral squamous cell carcinoma (OSCC), but existing deep learning methods OPI segmentation rely heavily on large, accurately labeled datasets, which labor- and resource-intensive to obtain. This paper presents a semi-supervised method mitigate the limitations of scarce data by leveraging both unlabeled data. Materials We use Hematoxylin Eosin (H&E)-stained dataset (OCDC), consists 451 with tumor regions annotated verified pathologists. Our combines transformation uncertainty multi-scale contrastive learning. The estimation evaluates model’s confidence transformed via different methods, reducing discrepancies between teacher student models. Multi-scale enhances class similarity separability while teacher-student model similarity, encouraging diverse feature representations. Additionally, boundary-aware enhanced U-Net is proposed capture boundary information improve accuracy. Results Experimental results OCDC demonstrate that our outperforms fully supervised approaches, achieving superior performance. Conclusions method, integrating uncertainty, learning, U-Net, effectively addresses scarcity improves approach reduces dependency large promoting application AI in OSCC detection improving efficiency accuracy clinical diagnoses OSCC.

Image segmentation is an important topic in computer vision, playing role wide range of applications such as medical image analysis, scene understanding, tumour boundary extraction among many others. aims to identify groups pixels and parts images that are similar belong together Semantic a classification with labels partitioning the objects. By applying segmentation, we can all objects image. The brain dataset utilizing for BRATS'20, which contains 317 images. proposed ensemble approach combining U-Net variants Mask RCNN models outperforms individual models. While method yielded improved Dice scores, using union six other methods achieved highest accuracy, indicated by superior scores. Specifically, model score 71.10 IoU 81.98. Additionally, demonstrated strong performance terms precision, reaching 84.96, recall value 81.90.
