Constructor & Destructor Documentation

IMP::em2d::CollisionCrossSection::CollisionCrossSection ( unsigned int  n_projections,
double  resolution,
double  pixel_size,
double  projection_image_size 
)
Parameters
[in]n_projectionsNumber of projections to use for obtaining the CCS
[in]resolution"Resolution" to use to generate the projections.
[in]pixel_sizesize in A/pix to use when generating the projections
[in]projection_image_sizeThe 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]mThe 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.

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

Particles used to calculate their collision cross section

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

Shows information about the class.

Parameters
outStream used to show the information
