Enforcing Monotonic Temporal Evolution in Dry Eye Images

Yedidya, Tamir; Carr, George Peter; Hartley, Richard; Guillon, Jean-Pierre

Description

We address the problem of identifying dry areas in the tear film as part of a diagnostic tool for dry-eye syndrome. The requirement is to identify and measure the growth of the dry regions to provide a time-evolving map of degrees of dryness. We segment dry regions using a multi-label graph-cut algorithm on the 3D spatio-temporal volume of frames from a video sequence. To capture the fact that dryness increases over the time of the sequence, we use a time-asymmetric cost function that enforces...[Show more]
