Rank-order filter
#include "dip_morphology.h"
dip_Error dip_PercentileFilter ( in, out, se, boundary, filterParam, shape, percentile )
integer, float
Rank-order or percentile filter with different filter shapes.
If shape is not equal to DIP_FLT_SHAPE_STRUCTURING_ELEMENT, se is allowed to be set to zero. When shape is set to DIP_FLT_SHAPE_STRUCTURING_ELEMENT, filterParam is ignored, (and can be set to zero).
| Data type | Name | Description |
| dip_Image | in | Input image |
| dip_Image | out | Output image |
| dip_Image | se | Structuring element |
| dip_BoundaryArray | boundary | Boundary conditions |
| dip_FloatArray | filterParam | Filter parameters |
| dip_FilterShape | shape | Filter shape |
| dip_float | percentile | Percentile (%) |
The enumerator dip_FilterShape contains the following constants:
| Name | Description |
| DIP_FLT_SHAPE_DEFAULT | default structuring element, same as DIP_FLT_SHAPE_RECTANGULAR |
| DIP_FLT_SHAPE_RECTANGULAR | rectangular structuring element |
| DIP_FLT_SHAPE_ELLIPTIC | elliptic structuring element |
| DIP_FLT_SHAPE_DIAMOND | diamond shaped structuring element |
| DIP_FLT_SHAPE_PARABOLIC | parabolic structuring element |
| DIP_FLT_SHAPE_STRUCTURING_ELEMENT | use se as structuring element |
The filter shape DIP_FLT_SHAPE_PARABOLIC, as well as custom grey-value shapes, are not supported.
