Exploring Temporal Constraints for Unsupervised Iris Motion Tracking in AS-OCT Videos

Lingxi Hu, Xiao Wu, Risa Higashita, Xiaoli Xing, Menglan Zhou, Song Lin +4

ICASSP 2025accepted

Iris motion tracking is critical for discriminating the iris stiffness and developmental stage of primary angle-closure disease (PACD). Anterior segment optical coherence tomography (AS-OCT) video is a highly efficient approach to observe the morphological determinant in iris motion. However, the ir…

Oct Image Blind Despeckling Based on Gradient Guided Filter with Speckle Statistical Prior

Sanqian Li, Muxing Xiong, Bing Yang, Xiaoqing Zhang, Risa Higashita, Jiang Liu

ICASSP 2023accepted

Optical coherence tomography (OCT) imaging technique has been widely used for ocular disease diagnosis. However, speckles occur in OCT images due to the property of coherent imaging, inevitably affecting the visual quality and clinical analysis. To alleviate this problem, we propose a novel gradient…
