void IMP::em2d::ProjectionFinder::do_preprocess_for_fast_coarse_registration	(	const cv::Mat &	m,
		algebra::Vector2D &	center,
		cv::Mat &	POLAR_AUTOC
	)

protected

Computes the weighted centroid and the FFT of the polar-resampled autocorrelation.

void IMP::em2d::ProjectionFinder::get_coarse_registration ( )

Coarse registration of all the images using the projections Based in 2D alignments of the images

Note: Given that this registration is based on 2D alignment maximizing the cross correlation, the a better score is the best correlation

void IMP::em2d::ProjectionFinder::get_complete_registration ( )

Performs complete registration of projections against the images. This means the coarse registration followed by simplex optimization

double IMP::em2d::ProjectionFinder::get_global_score ( ) const

Get the em2d score for a model after the registration performed: coarse or complete.

RegistrationResults IMP::em2d::ProjectionFinder::get_registration_results ( ) const

Recover the registration results. Only works if a registration has been done previously

void IMP::em2d::ProjectionFinder::set_fast_mode ( unsigned int n )

With this fast mode, only the first number n of best scoring projections during the coarse search are refined. Saves vast times of computation time with some loss of accuracy. Try starting with 1 (risky) or 2, and increase it to get more chances of finding the best projection

void IMP::em2d::ProjectionFinder::set_save_match_images ( bool x )

The projections of the model that best match the subject EM images are saved.

Their name will be: coarse-match-i.spi for coarse registration and fine_match-i.spi for full registration.
