-h | Help, prints usage message. |
-v | Verbose output with parameter values and execution time. |
-o | Output object file name. |
-m | Filter parameters; for a Gaussian these are the sigma values for each orthogonal direction (x, y and z). Default values are 1,1,1. |
-n | Order parameters; for a Gaussian these are the order of the Gaussian's derivatives (eg 0 for no derivative, 1 for 1st derivative), default 0,0,0. |
-g | Required grey type, default is the same as the input object's, with 'i', 's', 'u', 'f' and 'd' used to request int, short, unsigned byte, float or double grey values. |
-t | Filter directions, eg x filter along lines and x, y filter along lines then through columns. |
-P | Type of padding to use, default is to use the background value, with 'b', 'e', 'v' and 'z' used to select background, end, given value and zero padding. |
-p | Used to supply given padding value, default 0.0. |
-G | Use Gaussian filter, default. |
-S | Use the input object for each of the directional filters rather than the output of the previous directional filter. The seperate filter outputs are then combined to form a compound object (c), the sum (a) or the square root of the sum of the squared values of the filter passes (s). |
