Parameters

page

ImageGear.Core.ImGearRasterPage class object to be processed.

spreadFunctionVector

Vector which represents the Point Spread Function (PSF) in spatial domain, also called Degradation Function.

spreadFunctionVectorSize

Size of PSF passed in.

wienerConstant

The constant for Wiener Filtering.

Usually Wiener filtering can produce better results than inverse filtering.

Before using this method, like other frequency processing methods, InitializeFFTW method must be called first to initialize the support for FFTW.

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

Method ImGearFrequencyProcessingVerifier.CanApplyWienerRestore method can be called to check whether the operation can be performed or not.
