GeomDespeckle(ImGearRasterPage,Int32) Method

Reduces speckle noise from an image by using the Crimmins algorithm.

Syntax

'Declaration
 
Public Shared Sub GeomDespeckle( _
   ByVal page As ImGearRasterPage, _
   ByVal iterations As Integer _
)

'Usage
 
Dim page As ImGearRasterPage
Dim iterations As Integer
 
ImGearRasterProcessing.GeomDespeckle(page, iterations)

public static void GeomDespeckle( 
   ImGearRasterPage page,
   int iterations
)

public: static void GeomDespeckle( 
   ImGearRasterPage* page,
   int iterations
)

public:
static void GeomDespeckle( 
   ImGearRasterPage^ page,
   int iterations
)

page: An ImageGear.Core.ImGearRasterPage class object on which algorithm will be performed.
iterations: Number of iterations to apply the despeckle filter.

Remarks

This method reduces the speckle index of an image by sending the image through a geometric filter, which uses the complementary hulling technique.

The method has the effect of reducing the undesired speckle noise while preserving the edges of the original image.

Can be applied only to 8bit grayscale images with one channel.
