Terrain Matching by Fusing HOG With Zernike Moments
Kedong Wang, Han Wang, Jinling Wang · IEEE Transactions on Aerospace and Electronic Systems · 2019
A new matching algorithm is proposed by fusing the histogram of oriented gradients' and the Zernike moments' descriptors extracted from the real-time synthetic aperture radar (SAR) images and the real-time elevation maps (REMs), respectively. Both the SAR images and the REMs are acquired by an on-board interferometric SAR simultaneously. The two reciprocal descriptors are fused by weighting their Canberra distances. The numerical experiments demonstrate the advantage of the proposed matching algorithm preliminarily.
