Abstract

We analytically develop a filter that is able to measurethe linear stretch of the transformation around a point, and
present results of applying it to real signals. We show that
this method is a real-time alternative solution for measuring
local signal transformations. Experimentally, this method can
accurately measure stretch, however, it is sensitive to shift.
