Abstract

Local and global fit may be used to estimate radius of curvature. Computed radius shows high frequency noise in the local fit case and may be biased by the fitted model in the global case. Al priori knowledge may he used to impose constraints to the parametric model. To further improve radius estimation, splines are fitted to the filtered residue of the previous fit. Radius of curvature measurements by these methods, applied on cornea images, are analyzed in term of repeatability and justness.
