Intensity distribution topography on pupil"s image in EPR

Abstract: Eccentric photorefraction (EPR), which is used to determine the refractive error of eye, is greatly relied on the crescent pattern of the pupil image or on the intensity gradient in the principal meridian across the pupil. The vignetting image of the pupil, which is formed by a camera lens aperture with an eccentric light source, and contains a lot of refractive information of the subject eye, has been studied by many authors expecting to get more accurate measurement. In this paper, we have investigated the f… Show more

“…R Educing the time and cost associated with data labeling has posed a longstanding challenge for deploying large-scale deep models across various computer vision tasks [1], [2], [3], [4], [5], [6]. Several algorithms have been developed to address labeling costs, including semisupervised learning [7], weakly supervised learning [8], few-shot learning [9], and active learning [10].…”
