Implementation of the Hierarchical Discrete Radon Transform with Application to Image Registration.

摘要

This report discusses the background theory and implementation details of two new modules in the Analyst's Detection Support System (ADSS) environment. The first is the Hierarchical Discrete Radon Transform (HDRT), which provides a hierarchy of Radon transforms, from the Radon transform of single pixels in the image, right up to the Radon transform of the entire image. The second new module is an application of the HDRT to image registration. A coarse-to-fine strategy is implemented in order to handle local variations caused by terrain elevations and errors in global parameters. The use of the HDRT is fundamental to this multiresolution strategy.
