The motivation for discretising the derivative spaces of F-D curves is translational invariance, allowing us to find similar patterns of change in F-D curves that are translated with respect to each other. (a) The function c(x) = (x, sin(4x)) may fit a hypothetical path in an F-D curve. (b) The derivative space c'(x) = (1, 4 cos(4x)). (c) Hypothetical paths in two F-D curves that are translated with respect to each other will look similar in derivative space.
