Simultaneous Invariance with Respect to Translation, Rotation and Scaling

Abstract

In this chapter we wish to show how pattern recognition can be made invariant with respect to the above-mentioned transformations. To this end we write the test pattern vectors q and prototype pattern vectors υ k by means of their components and replace the discrete index j by the Cartesian coordinates x and y
$${q_j} \to q(x,y),{\upsilon _{kj}} \to {\upsilon _k}(x,y),$$
(8.1)
where q and υ represent for instance the value of grey tones at the position x,y.
