Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 6461 of file processor.h. 06462 {
06463 return "Replace a source image as a uniform random noise, random number generated from gsl_rng_mt19937, the pixel value is [0, 1)";
06464 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 6456 of file processor.h. 06457 {
06458 return NAME;
06459 }

Get processor parameter information in a dictionary. Each parameter has one record in the dictionary. Each record contains its name, data-type, and description.

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.
