摘要:

生物医学图像分割对于准确诊断和分析各类疾病至关重要。然而,该任务最常用的架构卷积神经网络(CNNs)和Transformer,由于CNNs固有的局部性和Transformer的计算复杂性,难以有效捕捉长程依赖关系。为解决这一局限,我们提出TTT-Unet,这是一种将测试时训练(TTT)层集成到传统U-Net架构中的新型框架,用于生物医学图像分割。TTT-Unet在测试时动态调整模型参数,增强模型捕捉局部和长程特征的能力。我们在多个医学成像数据集上评估TTT-Unet,包括CT和MR图像中的3D腹部器官分割、内窥镜图像中的器械分割以及显微图像中的细胞分割。结果表明,TTT-Unet在所有任务中持续优于最先进的基于CNN和Transformer的分割模型。代码可在https://github.com/rongzhou7/TTT-Unet获取。

英文摘要:

Biomedical image segmentation is crucial for accurately diagnosing and analyzing various diseases. However, Convolutional Neural Networks (CNNs) and Transformers, the most commonly used architectures for this task, struggle to effectively capture long-range dependencies due to the inherent locality of CNNs and the computational complexity of Transformers. To address this limitation, we introduce TTT-Unet, a novel framework that integrates Test-Time Training (TTT) layers into the traditional U-Net architecture for biomedical image segmentation. TTT-Unet dynamically adjusts model parameters during the testing time, enhancing the model's ability to capture both local and long-range features. We evaluate TTT-Unet on multiple medical imaging datasets, including 3D abdominal organ segmentation in CT and MR images, instrument segmentation in endoscopy images, and cell segmentation in microscopy images. The results demonstrate that TTT-Unet consistently outperforms state-of-the-art CNN-based and Transformer-based segmentation models across all tasks. The code is available at https://github.com/rongzhou7/TTT-Unet.
