Analysis of dense coregistration methods applied to optical and SAR time-series for ice flow estimations
International audience This article considers the application of two dense coregistration algorithms to the estimation of ice flow. These algorithms estimate displacements at each pixel of the image and can be applied to pairs of radar, optical and radar/optical images. This flexibility combined with...
