14.1: Comparison of Blur Edge Time and Gaussian Edge Time as Measures of Motion Blur

Blur Edge Time has been shown to be a reasonable metric for characterisation of motion blur of LCD displays. It can be estimated by taking the 10% to 90% level of the Moving Edge Temporal Profile or by using the standard deviation of a fitted cumulative Gaussian function. In this paper we will compare these two ways of estimating the Blur Edge Time. Ultimately the usefulness of these metrics of motion blur is whether they are good predictors of perceived motion blur.
