Constructor
| grid | Grid to be filtered. |
| interrupt | Optional interrupter. |
|
inline |
Shallow copy constructor called by tbb::parallel_for() threads during filtering.
| other | The other Filter from which to copy. |
| void gaussian | ( | int | width = 1, |
| int | iterations = 1, |
||
| const MaskType * | mask = nullptr |
||
| ) |
One iteration of a fast separable Gaussian filter.
| width | The width of the mean-value filter is 2*width+1 voxels. |
| iterations | Number of times the mean-value filter is applied. |
| mask | Optional alpha mask. |
|
inline |
|
inline |
|
inline |
Invert the optional mask, i.e. min->max in the original mask maps to 1->0 in the inverted alpha mask.
|
inline |
Return true if the mask is inverted, i.e. min->max in the original mask maps to 1->0 in the inverted alpha mask.
|
inline |
Return the maximum value of the mask to be used for the derivation of a smooth alpha value.
| void mean | ( | int | width = 1, |
| int | iterations = 1, |
||
| const MaskType * | mask = nullptr |
||
| ) |
One iteration of a fast separable mean-value (i.e. box) filter.
| width | The width of the mean-value filter is 2*width+1 voxels. |
| iterations | Number of times the mean-value filter is applied. |
| mask | Optional alpha mask. |
| void median | ( | int | width = 1, |
| int | iterations = 1, |
||
| const MaskType * | mask = nullptr |
||
| ) |
One iteration of a median-value filter.
| width | The width of the mean-value filter is 2*width+1 voxels. |
| iterations | Number of times the mean-value filter is applied. |
| mask | Optional alpha mask. |
|
inline |
Return the minimum value of the mask to be used for the derivation of a smooth alpha value.
| void offset | ( | ValueType | offset, |
| const MaskType * | mask = nullptr |
||
| ) |
Offsets (i.e. adds) a constant value to all active voxels.
| offset | Offset in the same units as the grid. |
| mask | Optional alpha mask. |
|
inline |
Used internally by tbb::parallel_for()
| range | Range of LeafNodes over which to multi-thread. |
|
inline |
Set the grain-size used for multi-threading.
|
inline |
Define the range for the (optional) scalar mask.
| min | Minimum value of the range. |
| max | Maximum value of the range. |
Mask values outside the range are clamped to zero or one, and values inside the range map smoothly to 0->1 (unless the mask is inverted).
| ValueError | if min is not smaller than max. |
|
inline |
Set whether active tiles should also be processed.
