摘要:

半监督学习是缓解医学图像分割标注数据稀缺问题的关键技术,但现有方法对形态异质性强、边界模糊的复杂医学图像分割效果仍不足。为此,本文提出一种基于双尺度纠缠互补学习的半监督分割算法。通过双尺度纠缠互补解码模块建立双尺度特征间的协同互补关系,实现结构信息的互补建模。其中,跨层融合编码模块强化浅层细节与深层语义特征的交互;多维特征优化模块增强解码阶段的空间结构与边缘细节重建能力。结合监督损失与扰动、尺度一致性损失,实现半监督训练。实验结果表明:本文算法在结肠镜息肉、皮肤病变及脑部肿瘤数据集上取得了较优的分割性能,在分割精度、边界平滑性及跨测试集泛化能力上均表现出良好的稳定性。

Abstract:

Semi-supervised learning serves as a core technique to address the scarcity of labeled data in medical image segmentation. However, existing methods struggle to achieve satisfactory segmentation results for complex medical images with high morphological heterogeneity and blurred boundaries. This paper proposes a semi-supervised segmentation algorithm based on Dual-Scale Entangled Complementary Learning. A Dual-Scale Entangled Complementary Decoder is constructed to establish collaborative complementary relationships between dual-scale features and realize complementary modeling of structural information. Specifically, the Cross-level Fusion Encoder Module strengthens the interaction between shallow detailed features and deep semantic features, while the Multi-Dimensional Feature Optimization Module improves the reconstruction capability of spatial structures and boundary details during decoding. Supervised loss together with perturbation and scale consistency losses are adopted to implement semi-supervised training. Experimental results demonstrate that the proposed algorithm achieves competitive segmentation performance on datasets of colon polyps, skin lesions and brain tumors, and maintains favorable stability in segmentation accuracy, boundary smoothness and cross-test-set generalization ability.

Key words: medical image segmentation, semi-supervised learning, entangled complementary decoder, cross-level fusion encoder, multi-dimensional feature optimization
