Constructor & Destructor Documentation

IMP::em2d::CollisionCrossSection::CollisionCrossSection	(	unsigned int	n_projections,
		double	resolution,
		double	pixel_size,
		double	projection_image_size
	)

Parameters

[in]	n_projections	Number of projections to use for obtaining the CCS
[in]	resolution	"Resolution" to use to generate the projections.
[in]	pixel_size	size in A/pix to use when generating the projections
[in]	projection_image_size	The size of the projections to generate; for this value you should request a size so that pixel_size * projection_image_size >= Max distance between two particles.

double IMP::em2d::CollisionCrossSection::get_ccs ( ) const

Returns the collision cross section. Before using this function you need to set the particles with set_model_particles()

double IMP::em2d::CollisionCrossSection::get_projected_area ( const cv::Mat & m ) const

protected

Gets the sum of the values in the pixels with value > 0

Parameters

[in] m The projected area is computed for this matrix

void IMP::em2d::CollisionCrossSection::set_model_particles ( const kernel::ParticlesTemp & ps )

kernel::Particles used to calculate their collision cross section

Parameters

ps	The particles

void IMP::em2d::CollisionCrossSection::show ( std::ostream & out ) const

Shows information about the class

Parameters

out	Stream used to show the information
