| Abstract(in English) | Organ segmentation is one of the most important branches of medical image analysis. Fully convolutional networks (FCNs) have become the dominant approach for this task and achieved considerable improvements for automated organ segmentation in volumetric image data, such as computed tomography images. In this paper, we investigate the influence of group normalization (GN) in multi-class organ segmentation from 3D CT volumes using fully convolutional network. Batch normalization is widely utilized in deep learning based methods to accelerate the convergence, reduce the reliance on initial learning rate and avoid overfitting. However, this type of normalization is strongly related to the batch size. Here, we study the influence of GN which is independent from batch size. In this research, we performed experiments on 377 cases of portal vein-phase abdominal CT volumes. The segmentation performance for small organs like artery and pancreas improved by introducing GN. |
