Separation-based model for low-dose CT image denoising
The Journal of Engineering, 2020 Low-dose computed tomography (LDCT) image often contains mottle noise and streak artefacts, which seriously interfere with clinical diagnosis. In this study, the separation-based (SEPB) method is proposed for mottle noise and streak artefacts suppression

Effect of Spatial Modulated Light on Position of Self-Calibration Point
IEEE Photonics Journal, 2021 In optical sensing, the differentiation between absorption and scattering poses a challenge when dealing with a physiological medium. We have shown that for extracting absorption-based parameters it is optimal to measure at the iso-path length (IPL ...
