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) |
