	abstract =	{The goal of this chapter is to illuminate to some extent
	the behaviour of some of the differential invariants and
	semi-invariants that are mentioned elsewhere in this volume. A
	straightforward implementation of Wilczynski's differential projective
	invariants $\Theta_3$ and $\Theta_8$, Weiss's differential
	semi-invariants $P_2$ and $P_3$, and Van Gool's semi-differential
	invariants $\tau_1(t)$ and $\tau_2(t)$ is used to give a qualitative
	idea of the behaviour of these invariants as a function of curve
	sampling rates and numerical precision in positional measurements. The
	results also give a qualitative feeling for how useful these invariant
	representations might be for matching and recognition.},
