Operator Library: Filter
The operator MEDIAN identifies and outputs the median value of an input kernel-stream. The kernel size is limited to 3x3 and 5x5.
| Link Parameter | Input Link I | Output Link O |
|---|---|---|
| Bit Width | [1, 64] | as I |
| Arithmetic | unsigned | as I |
| Parallelism | any | as I |
| Kernel Columns | {3, 5} | 1 |
| Kernel Rows | as kernel columns | 1 |
| Img Protocol | {VALT_IMAGE2D, VALT_LINE1D, VALT_PIXEL0D} | as I |
| Color Format | VAF_GRAY | as I |
| Color Flavor | FL_NONE | as I |
| Max. Img Width | any | as I |
| Max. Img Height | any | as I |
The use of operator MEDIAN is shown in the following examples:
-
Examples - The coprocessor feature of the microEnable IV VD1-CL is shown. As an example, a median filter is calculated.
-
Examples - Applet applies a 5x5 median filter on the image.
-
Examples - The examples shows an automatic dead pixel detection and replacement.
