WienerRestore Method

Description:

Performs image restoration using Wiener filtering in the frequency domain. This filter is also commonly referred to as the minimum mean square error filter or the least square error filter.

Usually speaking, Wiener filtering can produce better results than inverse filtering.

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

Syntax:

      WienerRestore(pPage As IGPage, PSFVector As IGDataArray,
dWienerConstant As double)

Parameters:

Name	Description
pPage	IGPage Object to be restored.
PSFVector	Double array which represents the Point Spread Function (PSF) in spatial domain, also called Degradation Function.
dWienerConstant	The constant for Wiener Filtering.

Return Value:

None

Bits Per Pixel:

8bit grayscale images with one channel
