FIL.SharpenImage
Enhances contrast of an image so that it appears sharper.
| Namespace: | FilNet |
|---|---|
| Assembly: | FIL.NET.dll |
Syntax
C++
C#
public static void SharpenImage ( FilNet.Image inImage, float inContrastFactor, FilNet.KernelShape inKernel, int inRadiusX, FilNet.Image outImage )
Parameters
| Name | Type | Range | Default | Description | |
|---|---|---|---|---|---|
 | inImage | FilNet.Image | Input image. | ||
| inContrastFactor | float | <0.0f, INF> | 1.0f | Value representing the strength of the contrast enhancement. Default value: 1.0f. |
| inKernel | FilNet.KernelShape | Kernel shape. | ||
| inRadiusX | int | <0, INF> | 1 | Nearly half of the kernel's width (2*R+1). Default value: 1. |
 | outImage | FilNet.Image | Output image. |
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.
