Image quality eigenfunctions in the human eye

Abstract

Numerical orthogonal and decorrelated basis functions for the ocular OTF have been developed. Our approach starts with a high dimensionality basis generated from the cross-correlation of complex Zernike polynomials. Single-value decomposition and principal component analysis are used to reduce dimensionality. The resulting basis functions have been applied to the reconstruction of individual OTFs from a dataset of normal eyes. Our results suggest that this reconstruction is feasible with a reasonable number of basis functions.
