Superresolution and singularities in phase images
Physics-Uspekhi, 2008The Rayleigh criterion and the Airy radius r0 are not adequate for characterizing spatial resolution in phase and some other functional images. An essential feature of phase images is a possible formation of wavefront dislocations which depend on the position in space of the so-called singular lines [I(x, y, z =0], in the neighborhood of which the ...

Scale-Space Phase Singularities
1992Chapter 9 discussed the stability of phase information using quantitative bounds on the expected variation of phase as a function of small scale perturbations of the input. But from Figure 9.1 it is also clear that phase stability is not uniform throughout scale-space; some regions exhibit much greater instability in that the phase contours are nearly ...
