Abstract

This paper studies the performance of various scale-invariant detectors in the context of feature matching. In particular, we propose an implementation of the Hessian-Laplace operator that we called Scale- Interpolated Hessian-Laplace. This research also proposes to use Haar descriptors which are derived from the Haar wavelet transform. It offers the advantage of being computationally inexpensive and smaller in size when compared to other descriptors.
