Member Function Documentation

string EMAN::NewHomomorphicTanhProcessor::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 734 of file processor_sparx.h.

00735                 {
00736                         return "Homomorphic Tanh processor applied in Fourier space";
00737                 }

string EMAN::NewHomomorphicTanhProcessor::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 730 of file processor_sparx.h.

00731                 { return NAME; }

TypeDict EMAN::NewHomomorphicTanhProcessor::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.

Definition at line 732 of file processor_sparx.h.

00733                 { return new NewHomomorphicTanhProcessor(); }

void EMAN::NewHomomorphicTanhProcessor::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.
