MAF-Net: Multiple attention-guided fusion network for fundus vascular image segmentation

no code implementations5 May 2023 Yuanyuan Peng, Pengpeng Luan, Zixu Zhang

To enrich contextual information for the loss of scene information compensation, an attention fusion mechanism that combines the channel attention with spatial attention mechanisms constructed by Transformer is employed to extract various features of blood vessels from retinal fundus images.

Curvilinear object segmentation in medical images based on ODoS filter and deep learning network

no code implementations18 Jan 2023 Yuanyuan Peng, Lin Pan, Pengpeng Luan, Hongbin Tu, Xiong Li

Automatic segmentation of curvilinear objects in medical images plays an important role in the diagnosis and evaluation of human diseases, yet it is a challenging uncertainty in the complex segmentation tasks due to different issues such as various image appearances, low contrast between curvilinear objects and their surrounding backgrounds, thin and uneven curvilinear structures, and improper background illumination conditions.

Pulmonary Fissure Segmentation in CT Images Based on ODoS Filter and Shape Features

no code implementations23 Jan 2022 Yuanyuan Peng, Pengpeng Luan, Hongbin Tu, Xiong Li, Ping Zhou

Here, we adopt an ODoS filter by merging the orientation information and magnitude information to highlight structure features for fissure enhancement, which can effectively distinguish between pulmonary fissures and clutters.
