Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 4006 of file processor.h. 04007 { 04008 return "First call filter.ramp on the image, then make the mean 0 and norm 1"; 04009 }

Get the processor's name. Each processor is identified by a unique name.

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.
