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.

Member Function Documentation

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()

Returns

The collision cross section

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

Returns

Values of the area

virtual ::IMP::VersionInfo IMP::em2d::CollisionCrossSection::get_version_info ( ) const

overridevirtual

Get information about the module and version of the object.

Reimplemented from IMP::Object.
