Abstract
.In this paper a fast registration of remote sensing image with polar sin transform based descriptor is proposed. The main characteristics of the proposed method include: (1) Several new methods are presented to realize fast and accurate interest points extraction under various different scenes, include image scale space construction based on integral image, interest points controlling based on uniform distribution, (2) Through comparing the euclidean distance of the PST (polar sin transform) descriptors defined on the corner neighborhoods, the corresponding matches are established. Experiment results illustrate that the proposed algorithm carries out real-time image registration and is robust to large image translation, scaling and rotation.
