Member Function Documentation

◆ get_desc()

string EMAN::BinaryInternalGradientProcessor::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 1419 of file processor.h.

1420 {
1421 return "Computes an internal morphological graduent using k-pixel-width operations on a (binary) image.";
1422 }

◆ get_name()

string EMAN::BinaryInternalGradientProcessor::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 1405 of file processor.h.

1406 {
1407 return NAME;
1408 }

References NAME.

◆ get_param_types()

TypeDict EMAN::BinaryInternalGradientProcessor::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 1424 of file processor.h.

1426 TypeDict d;
1427 d.put("radius", EMObject::INT, "The number of pixels (radius) to dilate the input image.");

1429 d.put("thresh", EMObject::FLOAT,"Only considers densities above the threshold");
1430 return d;

◆ process()

EMData * BinaryInternalGradientProcessor::process ( const EMData *const  image)
virtual

To proccess an image out-of-place.

For those processors which can only be processed out-of-place, override this function to give the right behavior.

Parameters
imageThe image will be copied, actual process happen on copy of image.
Returns
the image processing result, may or may not be the same size of the input image

Reimplemented from EMAN::Processor.

Definition at line 15281 of file processor.cpp.

15283 EMData* proc = image->copy();
15284 proc->process_inplace("morph.gradient.internal",params);
15285 return proc;
15286}
EMData stores an image's data and defines core image processing routines.
Definition: emdata.h:82

References EMAN::Processor::params.

◆ process_inplace()

void BinaryInternalGradientProcessor::process_inplace ( EMData image)
virtual

To process an image in-place.

For those processors which can only be processed out-of-place, override this function to just print out some error message to remind user call the out-of-place version.

Parameters
imageThe image to be processed.

Implements EMAN::Processor.
