This chapter proposes a new approach for learning invariant region descriptor operators through genetic programming. The approach relies on the synthesis of mathematical expressions that extract information derived from local image patches. These local features have been previously designed by human experts using traditional representations that have a clear and, preferably, mathematically wellfounded definition. We propose in this chapter that the mathematical principles that are used in the description of such local features could be evolved with the genetic programming paradigm to find a set of features that exhibit an optimal local description. Experimental results confirm the validity of our approach using a widely accepted testbed that is used for testing local descriptor algorithms. Furthermore, we provide results that illustrate the performance of our improved SIFT algorithm using an object recognition application for indoor and outdoor scenarios.
