Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 3202 of file processor.h. 03203 { 03204 return "averages over cal_half_width, then sets the value in a local block"; 03205 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 3193 of file processor.h. Referenced by process_inplace(). 03194 {

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.
