dip_Error dip_ErfClip ( in, out, threshold, range, clipFlag )
integer, float
Clips in using the erf function at either or both the values threshold +/- range/2. If the flag DIP_CLIP_LOW_AND_HIGH_BOUNDS is specified, threshold and range are used as lower and upper bounds respectively.
| Data type | Name | Description |
| dip_Image | in | Input image |
| dip_Image | out | Output image |
| dip_float | threshold | Threshold value |
| dip_float | range | Range value |
| dipf_Clip | clipFlag | clipFlag |
The following dipf_Clip flags are defined:
| Name | Description |
| DIP_CLIP_BOTH | clip both the lower and upper bound |
| DIP_CLIP_LOW | clip lower bound only |
| DIP_CLIP_HIGH | clip upper bound only |
| DIP_CLIP_THRESHOLD_AND_RANGE | same as DIP_CLIP_BOTH |
| DIP_CLIP_LOW_AND_HIGH_BOUNDS | use threshold and range as lower and upper bounds |
