                 detectors that are based on image operators synthesised
                 through Genetic Programming (GP). Interesting or
                 salient regions on an image are of considerable
                 usefulness within a broad range of vision problems,
                 including, but not limited to, stereo vision, object
                 detection and recognition, image registration and
                 content-based image retrieval. A GP-based framework is
                 described where candidate image operators are
                 synthesized by employing a fitness measure that
                 promotes the detection of stable and dispersed image
                 features, both of which are highly desirable
                 properties. After a significant number of experimental
                 runs, a plateau of maxima was identified within the
                 search space that contained operators that are similar,
                 in structure and/or functionality, to basic LoG or DoG
                 filters. Two such operators with the simplest structure
                 were selected and embedded within a linear scale space,
                 thereby making scale-invariant feature detection a
                 straightforward task. The proposed scale-invariant
                 detectors exhibit a high performance on standard tests
                 when compared with state-of-the-art techniques. The
                 experimental results exhibit the ability of GP to
                 construct highly reusable code for a well known and
                 hard task when an appropriate optimisation problem is
