Cross-Correlation Stacking for Robust Offset Tracking Using SAR Image Time-Series
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021 Offset tracking is widely applied for measuring ground surface displacements from remote sensing data. Displacements are determined by the offset where two image templates match best. The match can be evaluated with normalized cross correlation (NCC), in

Glacier motion estimation using SAR offset-tracking procedures [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2002 Two image-to-image patch offset techniques for\ud estimating feature motion between satellite synthetic aperture radar (SAR) images are discussed. Intensity tracking, based on patch intensity cross-correlation optimization, and coherence tracking, based on patch coherence optimization, are used to estimate the movement of glacier surfaces between two ...
