Abstract Semantic Segmentation has been widely used in a variety of clinical images, which greatly assists medical diagnosis and other work. To address the challenge reduced semantic inference accuracy caused by feature weakening, pioneering network called FTUNet (Feature-enhanced Transformer UNet) was introduced, leveraging classical Encoder-Decoder architecture. Firstly, dual-branch Encoder is proposed based on U-shaped structure. In addition to employing convolution for extraction, Layer...

Multi-task semantic communication can serve multiple learning tasks using a shared encoder model. Existing models have overlooked the intricate relationships between features extracted during an encoding process of tasks. This paper presents new graph attention inter-block (GAI) module to encoder/transmitter multi-task system, which enriches for by embedding intermediate outputs in features, compared existing techniques. The key idea is that we interpret feature extraction blocks as nodes...

Magnetic resonance (MR) images are usually limited by low spatial resolution, which leads to errors in post-processing procedures. Recently, learning-based super-resolution methods, such as sparse coding and convolution neural network, have achieved promising reconstruction results scene images. However, these methods remain insufficient for recovering detailed information from low-resolution MR due the size of training dataset.To investigate different edge responses using kernel sizes, this...
