Notes for Affine Transform-based Vtln

Abstract

These are some notes on a linear transform based approximation to VTLN. It describes how, given a small amount of data for which we have the original and “conventionally warped” features, we can obtain a transform that approximates the original warping and leaves the mean and covariance of the sample data unchanged.
