SharpenImage
Enhances contrast of an image so that it appears sharper.
| Name | Type | Range | Description | |
|---|---|---|---|---|
 |
inImage | Image | Input image | |
|
inContrastFactor | Real | 0.0 -  |
Value representing the strength of the contrast enhancement |
|
inKernel | KernelShape | Kernel shape | |
|
inRadiusX | Integer | 0 - |
Nearly half of the kernel's width (2*R+1) |
|
inRadiusY | Integer* | 0 - |
Nearly half of the kernel's height (2*R+1), or same as inRadiusX |
 |
outImage | Image | Output image | |
Applications
Description
This filter increases the contrast of the image by multiplying by inContrastFactor the difference between a pixel value and its corresponding pixel value in the smoothed input image:
\[ \begin{aligned} outImage[i,j] &= inImage[i,j] + inContrastFactor \times (inImage[i,j] - smoothedImage[i,j]) \\ \end{aligned} \]Examples
 |
 |
SharpenImage run on example image with inContrastFactor = 2.
