SSCA-Net: Simultaneous Self- and Channel-Attention Neural Network for Multiscale Structure-Preserving Vessel Segmentation

Abstract: Vessel segmentation is a fundamental, yet not well-solved problem in medical image analysis, due to the complicated geometrical and topological structures of human vessels. Unlike existing rule- and conventional learning-based techniques, which hardly capture the location of tiny vessel structures and perceive their global spatial structures, we propose Simultaneous Self- and Channel-attention Neural Network (termed SSCA-Net) to solve the multiscale structure-preserving vessel segmentation (MSVS) problem. SSCA… Show more

“…In the traditional convolutional neural network, continuous convolution and pooling operations will lead to a decrease in image resolution and the loss of spatial structure information, which has a great impact on the task of medical image segmentation, and directly lead to the blurred boundary and pixel classification errors after segmentation. With the appearance of atrous spatial pyramid pooling (ASSP) structure (Chen et al, 2018b), the above problems can be solved well, and many optimized models are proposed continuously (Ni et al, 2021;Xie et al, 2021;Lan et al, 2022;Liang et al, 2022). By connecting convolution layers with different expansion rates in parallel, ASSP can alleviate the problem of spatial information loss caused by Frontiers in Physiology frontiersin.org downsampling, and enlarge the receptive field without increasing the amount of computation, to obtain more regional information.…”

“…Just like the mentioned points in Section 2.2, to take both traditional NSS and GCS priors into account in the network, we introduce two attention mechanisms, i.e., spatial attention and spectral attention [55][56][57][58] which could approximate the NSS and GCS characteristics in a sense, respectively. Specifically, NSS across space is to investigate the spatial similarity between image patches (even pixels).…”
