Member Function Documentation

string EMAN::NewHomomorphicButterworthProcessor::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 552 of file processor_sparx.h.

00553                 {
00554                         return "Homomorphic Butterworth filter processor applied in Fourier space.";
00555                 }

string EMAN::NewHomomorphicButterworthProcessor::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 548 of file processor_sparx.h.

References NAME.

00549                 { return NAME; }

TypeDict EMAN::NewHomomorphicButterworthProcessor::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.

00551                 { return new NewHomomorphicButterworthProcessor(); }

void EMAN::NewHomomorphicButterworthProcessor::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:
image The image to be processed.

Implements EMAN::Processor.
