Member Function Documentation

◆ get_desc()

string EMAN::PeakOnlyProcessor::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 4729 of file processor.h.

4730 {
4731 return "Zeros all pixels with adjacent pixels >= the value being considered. That is, it leaves behind only local maxima.";
4732 }

◆ get_name()

string EMAN::PeakOnlyProcessor::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 4704 of file processor.h.

4705 {
4706 return NAME;
4707 }
static const string NAME
Definition: processor.h:4734

References NAME.

◆ get_param_types()

TypeDict EMAN::PeakOnlyProcessor::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::BoxStatProcessor.

Definition at line 4721 of file processor.h.

4722 {
4723 TypeDict d;
4724 d.put("npeaks", EMObject::INT, "The number of pixels adjacent to the pixel under consideration which may be higher and still be a valid peak. If 0, finds pure peaks");
4725 d.put("usemean", EMObject::BOOL, "Count all pixels with value higher than the mean of adjacent pixels as peaks. Overwrite npeaks.");
4726 return d;
4727 }
TypeDict is a dictionary to store <string, EMObject::ObjectType> pair.
