Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings. With reference to the accompanying drawings in the description, the specific implementation of the present invention is divided into the following steps:
[0019] (1) Design a frequency-domain Log-Gabor filter, perform Log-Gabor filtering on the reference image and the image to be registered, obtain the frequency-domain response of the Log-Gabor filter, and obtain three components of the single-cast signal, based on the following formula
[0020] f p (x,y,s)=I*F -1 (G(ω))
[0021] H=F(f p (x, y, s))
[0022] f x ( x , y , s ) = F - 1 ( ( - 1 ...
