Detection and removal of dust artifacts in retinal images via sparse-based inpainting
(2021-09-06)
Dust particle artifacts are present in all imaging modalities but have more adverse consequences in
medical images like retinal images. They could be mistaken as small lesions, such as microaneurysms.
We propose a method ...
Method for large-scale structured-light system calibration
(2021-05-24)
We propose a multi-stage calibration method for increasing the overall accuracy of a
large-scale structured light system by leveraging the conventional stereo calibration approach
using a pinhole model. We first calibrate ...
