SmoothImage_Median
Replaces each pixel with the median of pixels within a kernel.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inImage | Image | Input image | |
|
inRoi | Region* | Range of outImage pixels being written | |
|
inSourceRoi | Region* | Range of inImage pixels being read | |
|
inKernel | SmoothImageMedianKernel | ||
|
inRadius | Integer | 0 -  |
Nearly half of the kernel's size (2*R+1) |
 |
outImage | Image | Output image | |
Only the following inImage pixel formats are supported: uint8
Applications
Edge-preserving noise removal (but slow).
Hints
- Define the kernel size by setting the inRadius input.
- For small kernels consider switching to SmoothImage_Median_Mask to achieve higher performance.
Examples
 |
 |
SmoothImage_Median performed on a sample image with inRadius = 4.
