GLOF-SFE

Global Luminescent Oil Film image based Skin friction Field Estimator

Description

This is an image analysis toolbox for estimation of high-resolution skin friction field from flow visualization (global luminescent oil film, GLOF) images.

Detail of the method is described in following paper.
