Phase unwrapping of SAR interferogram based on dyadic wavelets
IEEE International Geoscience and Remote Sensing Symposium - Tập 4 - Trang 2537-2539 vol.4
Tóm tắt
A new phase unwrapping algorithm based on fringe line detection is presented. Dyadic wavelet theory is used to extract the multi-scale edge of an SAR interferogram. The phase characteristic of the interferogram are derived utilizing an active contour algorithm of the gradient vector flow.
