Member Function Documentation

◆ get_desc()

string EMAN::DiscritizeProcessor::get_desc ( ) const

inlinevirtual

Get the descrition of this specific processor.

This function must be overwritten by a subclass.

Returns: The description of this processor.

Implements EMAN::Processor.

Definition at line 2571 of file processor.h.

                {
                        return "Converts each pixel value to the integral number of standard deviations from the specified center. Rounds to the nearest integer, -0.5*sigma<x<0.5*sigma -> 0.0  ";
                }

◆ get_name()

string EMAN::DiscritizeProcessor::get_name ( ) const

inlinevirtual

Get the processor's name.

Each processor is identified by a unique name.

Returns: The processor's name.

Implements EMAN::Processor.

Definition at line 2544 of file processor.h.

                {
                        return NAME;
                }

References NAME.

◆ get_param_types()

TypeDict EMAN::DiscritizeProcessor::get_param_types ( ) const

inlinevirtual

Get processor parameter information in a dictionary.

Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

Returns: A dictionary containing the parameter info.

Reimplemented from EMAN::Processor.

Definition at line 2563 of file processor.h.

                        {
                                TypeDict d;
                                d.put("center", EMObject::FLOAT, "Center value from which number of standard deviations is computed (default = 0)");
                                d.put("step", EMObject::FLOAT, "Stepsize in terms of sigma. ie - 1.5 will discritize to 1.5*sigma steps (default = 1.0)");
                                return d;
                        }

Implements EMAN::RealPixelProcessor.

Definition at line 2581 of file processor.h.

                {
                        *x = Util::fast_floor((*x-center)/(step*sigma)+0.5)*step;
                }

References center, EMAN::Util::fast_floor(), EMAN::RealPixelProcessor::sigma, step, and x.

◆ set_params()

void EMAN::DiscritizeProcessor::set_params ( const Dict & new_params )

inlinevirtual

Set the processor parameters using a key/value dictionary.

Parameters

new_params A dictionary containing the new parameters.
