Abstract: In this paper we propose an efficient interest points detection algorithm that is
invariant to scale, rotation and translation as well as robust to illumination changes and limited
changes of viewpoint. First, we compute one pyramid representation in which every layer is used
to detect the initial points with the Harris detector. Second, we compute another pyramid
representation based on the difference of Gaussians in which the stable points are determined
with the local maximum over adjacent layers. For a local structure in an image, the proposed
algorithm can detect interest points in a certain range of scales to represent this local feature,
and the localizations of these points are slightly different. Thus, the algorithm can obtain the high
number of interest points and increase the probability of correct matches between the gradual
transformation images of the same scene. We present a comparative evaluation between the
proposed algorithm and the Harris-Laplace detector, and show the proposed algorithm not only
obtains high matching scores but also consumes less time for different scenes.
