Classification: CPC G  A | IPC A  G

Claim 4:
5. The imaging method according to claim 4, wherein the even-symmetric band-pass filter is a log-Garbor radial filter,
the two consecutive odd-symmetric filters correspond to the Riesz transform of the log-Garbor radial filter,
wherein three uniformly decreasing center-frequency are used for the band-pass for the log-Garbor filter, using 30, 20 and 10 pixels, which defines three consecutive scales,
wherein at each scale, 20 iterations are performed and the similarity function with each local phase scale is evaluated, and
wherein the final-scale motion field is regularized with a Gaussian low-pass kernel with a Full-Width at Half-Maximum of 10 pixels.
