Detailed Description

Iterative rotational, translational alignment with flipping and scaling.

Basically, we find the best translation, and move to that pointer then we find the best rotation and rotate to that point. Next we iterate X times. We do this for each scale and flip of the image and return the optimal solution

Parameters:
min Minimum scaling (default: 0.95)
max aximum scaling (default: 1.05)
step Scaling step (default: 0.01)
flip 
maxshift Maximum translation in pixels
r1 inner ring
r2 outer ring
maxiter maximum number of alignment iterations

EMData * RotateTranslateFlipScaleAlignerIterative::align ( EMData this_img,
EMData to_img,
const string &  cmp_name = "dot",
const Dict cmp_params = Dict() 
) const [virtual]

To align 'this_img' with another image passed in through its parameters.

The alignment uses a user-given comparison method to compare the two images. If none is given, a default one is used.

Parameters:
this_img The image to be compared.
to_img 'this_img" is aligned with 'to_img'.
cmp_name The comparison method to compare the two images.
cmp_params The parameter dictionary for comparison method.
Returns:
The aligned image.
