Since the advent of U-Net, fully convolutional deep neural networks and its many variants have completely changed the modern landscape of deep learning based medical image segmentation. However, the over dependence of these methods on pixel level classification and regression has been identified early on as a problem. Especially when trained on medical databases with sparse available annotation, these methods are prone to generate segmentation artifacts such as fragmented structures… Expand

Study on MRI Medical Image Segmentation Technology Based on CNN-CRF Model
TLDR
A cascading structure is added under the deep convolutional neural networks (DCNN) framework to more effectively simulate the direct dependencies between spatial closure tags and the conditional random field (CRF) is used for post-segmentation processing, which effectively solves the contradiction between the segmentation accuracy and the network depth and the number of pooling times in the traditional convolutionals.
