virtual void | process_pixel (float *pixel, const float *array, int n) const =0 |
These processors compute every output pixel using information from a reduced region on the neighborhood of the input pixel. The classical form are the 3x3 processors. BoxStatProcessors could perform diverse tasks ranging from noise reduction, to differential , to mathematical morphology. BoxStatProcessor class is the base class. Specific BoxStatProcessor needs to define process_pixel(float *pixel, const float *array, int n).
radius | The radius of the search box, default is 1 which results in a 3x3 box (3 = 2xradius + 1) |

static string EMAN::BoxStatProcessor::get_group_desc | ( | ) | [inline, static] |
Get the description of this group of processors.
This function is defined in a parent class. It gives a introduction to a group of processors.

void BoxStatProcessor::process_inplace | ( | EMData * | image | ) | [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.
image | The image to be processed. |
