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

align() [2/2]

virtual EMData * EMAN::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.

Implements EMAN::Aligner.
