Abstract

In this paper we present an algorithm for estimating camera system modulation transfer functions (MTF) from highly distorted images. This algorithm estimates multiple oversampled line spread functions using different order polynomials and binning. The ensemble of oversampled line spread functions (LSF) are used to estimate the final system MTF. Moreover, the LSF derived from the highest order polynomial without overfitting is used to estimate the system MTF. We show the performance of this algorithm on synthetically generated images and on image captures from a commercially available camera. We compare this algorithm to the ISO 12233 standard.
