New Freeware for Image Analysis of Lissamine Green Conjunctival Staining.

Purpose: Lissamine green (LG) is often used in addition to fluorescein to assess the severity of conjunctival damage in dry eye syndrome, which is graded manually. Our purpose was to describe an algorithm designed for image analysis of LG conjunctival staining.

Methods: Twenty pictures of patients suffering from dry eye with visible LG conjunctival staining were selected.

Local low rank approximation with a parametric disparity model for light field compression.

We address the problem of light field dimensionality reduction for compression. We describe a local low rank approximation method using a parametric disparity model. The local support of the approximation is defined by super-rays.
