Algorithms for the Construction of Invariant Features
Hanns Schulz-Mirbach · 1994
The paper presents algorithms for the construction of features which are invariant with respect to a given transformation group. The methods are based on integral calculus and are applicable to parametric groups (Lie groups) and finite groups as well. To illustrate the concepts we discuss in detail how to construct invariant features for the general linear group which is of importance in computer vision applications. We describe how to combine the algorithms with Hilbert space methods for the description of continuous signals.
