Member Function Documentation

string EMAN::NewHomomorphicTopHatProcessor::get_desc ( ) const [inline, virtual]

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 287 of file processor_sparx.h.

                {
                        return "Homomorphic top-hat filter processor applied in Fourier space.";
                }
string EMAN::NewHomomorphicTopHatProcessor::get_name ( ) const [inline, virtual]

Get the processor's name.

Each processor is identified by a unique name.

Returns:
The processor's name.

Implements EMAN::Processor.

Definition at line 283 of file processor_sparx.h.

References NAME.

                { return NAME; }
TypeDict EMAN::NewHomomorphicTopHatProcessor::get_param_types ( ) const [inline, virtual]

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::NewFourierProcessor.

static Processor* EMAN::NewHomomorphicTopHatProcessor::NEW ( ) [inline, static]

Definition at line 285 of file processor_sparx.h.

                { return new NewHomomorphicTopHatProcessor(); }
void EMAN::NewHomomorphicTopHatProcessor::process_inplace ( EMData image) [inline, 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.
