abstract = "Nowadays, object recognition based on local invariant
features is widely acknowledged as one of the best
paradigms for object recognition due to its robustness
for solving image matching across different views of a
given scene. This paper proposes a new approach for
learning invariant region descriptor operators through
genetic programming and introduces another optimisation
method based on a hill-climbing algorithm with multiple
re-starts. The approach relies on the synthesis of
mathematical expressions that extract information
derived from local image patches called local features.
These local features have been previously designed by
human experts using traditional representations that
have a clear and, preferably mathematically,
well-founded definition. We propose in this paper that
the mathematical principles that are used in the
description of such local features could be well
optimised using a genetic programming paradigm.
Experimental results confirm the validity of our
approach using a widely accepted testbed that is used
for testing local descriptor algorithms. In addition,
we compare our results not only against three
state-of-the-art algorithms designed by human experts,
but also, against a simpler search method for
automatically generating programs such as hill-climber.
Furthermore, we provide results that illustrate the
performance of our improved SIFT algorithms using an
object recognition application for indoor and outdoor
scenarios.",
