GeomDespeckle Method

Description:

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

This method takes into account the ROI settings of pPage object, that are accessible via the IGPage.ROI property. By default ROI is set to the entire image.

Syntax:

      GeomDespeckle(pPage As IGPage, nIterations As Long);

Parameters:

Name	Description
pPage	IGPage object to despeckle.
nIterations	Number of iterations to apply the despeckle filter.

Return Value:

N/A

Bits Per Pixel:

8 bit grayscale images with one channel
