Lightweight Non-Local Network for Image Super-Resolution

Risheng Wang, Tao Lei, Wenzheng Zhou, Qi Wang, Hongying Meng, Asoke K. Nandi

ICASSP 2021accepted

The popular deep convolutional networks used for image super-resolution (SR) reconstruction often increase the network depth and employ attention mechanism to improve image reconstruction effect. However, these networks suffer from two problems. The first is the deeper network easily causes higher c…

Lightweight V-Net for Liver Segmentation

Tao Lei, Wenzheng Zhou, Yuxiao Zhang, Risheng Wang, Hongying Meng, Asoke K. Nandi

ICASSP 2020accepted

The V-Net based 3D fully convolutional neural networks have been widely used in liver volumetric data segmentation. However, due to the large number of parameters of these networks, 3D FCNs suffer from high computational cost and GPU memory usage. To address these issues, we design a lightweight V-N…
