Synopsis

Keywords: Data Processing, SegmentationDue to the inherent locality of convolutional operations, convolution neural network (CNN) often exhibits limitations in explicitly modeling long-distance dependencies. In this paper, we propose a novel hybrid multi-level graph neural (HMGN) network that combines the CNN and graph neural network to capture both local and non-local image features at multiple scales. With the proposed patch graph attention module, the HMGN network can capture image features over a large receptive field, resulting in more accurate segmentation of cardiac structures. Experiments on two public datasets show the proposed method obtains improved segmentation performance over the state-of-the-art methods.
