Visible motion blur

Abstract

A method of measuring motion blur is disclosed comprising obtaining a moving edge temporal profile r(k) of an image of a high-contrast moving edge, calculating the masked local contrast m(k) for r(k) and the masked local contrast m(k) for an ideal step edge waveform r(k) with the same amplitude as r(k), and calculating the measure or motion blur Ψ as a difference function,Ω=(Δ()−()|).The masked local contrasts are calculated using a set of convolution kernels scaled to simulate the performance of the human visual system, and Ψ is measured in units of just-noticeable differences.
