Detailed Description

f(x) = 0 if x < value; f(x) = 1 if x >= value.

Parameters

value

The thresholding value. If a pixel value is equal to or above the threshold it is set to 1. If it is below it is set to 0

Member Function Documentation

get_desc()

string EMAN::BinarizeProcessor::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 3208 of file processor.h.

                {
                        return "f(x) = 0 if x < value; f(x) = 1 if x >= value.";
                }

get_name()

string EMAN::BinarizeProcessor::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 3193 of file processor.h.

                {
                        return NAME;
                }

References NAME.

get_param_types()

TypeDict EMAN::BinarizeProcessor::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.
