Interferometric SAR image coregistration based on the Fourier-Mellin invariant descriptor

The problem of interferometric SAR image coregistartion is addressed. For classical images, the application of the Symmetric Phase Only Matching Filtering (SPOMF) to the Fourier-Mellin Invariant (FMI) descriptors allows an accurate and efficient registration of translated, rotated and scaled images. This paper discusses an extension of the technique to cover the FMI descriptors of two interferometric SAR images. This method is tested on two pairs of InSAR data in France and Tunisa. The results are compared with those of classical cross-correlation registration techniques.
