Member Function Documentation

get_desc()

string EMAN::BinaryClosingProcessor::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 1335 of file processor.h.

                {
                        return "Performs a morphological k-pixel closing of a (binary) image/volume. Note the box must be large enough to accommodate the dilation to work properly. iter(dilate) -> iter(erode)";
                }

get_name()

string EMAN::BinaryClosingProcessor::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 1321 of file processor.h.

                {
                        return NAME;
                }

References NAME.

get_param_types()

TypeDict EMAN::BinaryClosingProcessor::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.

process()

EMData * BinaryClosingProcessor::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

image

The 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 15264 of file processor.cpp.

{
        EMData* proc = image->copy();
        proc->process_inplace("morph.close.binary",params);
        return proc;
}

References EMAN::Processor::params.

process_inplace()

void BinaryClosingProcessor::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

image

The image to be processed.

Implements EMAN::Processor.
