Abstract :
Interest point detection and matching is a basic computer vision task. This paper uses the Non-Subsampled Contourlet Transform (NSCT) detector with some local descriptors to develop a robust Interest point matching system. The NSCT-based detector is very efficient in extracting relevant image features that have good localization and rich geometric information. Once interest points have been extracted, invariant descriptors can be computed to represent these points and match them by comparing their descriptors using similarity distance metric measure. Several experiments have been conducted on a variety of datasets that compare the proposed approach to the widely used Harris and Hessian detectors with the same local descriptors. The results show that the NSCT method is efficient in natural scenes with distinctive texture, occlusion and clutter objects. It offers robustness for detecting points in blurred images. It is also invariant to rotation, translation, and partially invariant to scale and viewpoint angle changes.
