The Filter library includes filter operators for any kind of image filters and kernel operations. For practical guidance on working with kernels in designs, see the Working with Kernels Tutorial topic.
The following list summarizes all Operators of Library Filter
| Operator Name | Short Description | available since | |
|---|---|---|---|
 |
DILATE |
Performs a binary dilation of the image, which can be used to close gaps in images. |
Version 1.1 |
 |
ERODE |
Performs a binary erosion of the image, which can be used to separate touching objects. |
Version 1.1 |
 |
FIRkernelNxM |
Creates rectangular kernel window around each pixel, which includes the neighbor pixels. |
Version 1.1 |
 |
FIRoperatorNxM |
Calculates the sum of the multiplication of the input kernel elements with parameterizable coefficients. |
Version 1.1 |
 |
HitOrMiss |
Implements the morphological image processing operator hit-or-miss as matching element with defined structure. |
Version 1.2 |
 |
LineNeighboursNx1 |
Creates a kernel window of N rows and 1 column. |
Version 1.2 |
 |
MAX |
Identifies and outputs the maximum value of an input kernel-stream. |
Version 1.1 |
 |
MEDIAN |
Identifies and outputs the median of an input kernel-stream. |
Version 1.1 |
 |
MIN |
Identifies and outputs the minimum value of an input kernel-stream. |
Version 1.1 |
 |
NumberOfHits |
Counts the number of matches of the input kernel with a defined structure. |
Version 1.2 |
 |
PixelNeighbours1xM |
Creates a kernel window of 1 row and M columns. |
Version 1.2 |
 |
SORT |
Sorts all elements of an input kernel-stream by their gray values. |
Version 1.2 |
