Get the descrition of this specific processor. This function must be overwritten by a subclass.
Implements EMAN::Processor. Definition at line 3108 of file processor.h. 03109 { 03110 return "averages over cal_half_width, then sets the value in a local block"; 03111 }

Get the processor's name. Each processor is identified by a unique name.
Implements EMAN::Processor. Definition at line 3099 of file processor.h. Referenced by process_inplace(). 03100 {
03101 return NAME;
03102 }

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.
