C# 클래스 Accord.Imaging.ComplexFilters.FrequencyFilter

Filtering of frequencies outside of specified range in complex Fourier transformed image.

The filer keeps only specified range of frequencies in complex Fourier transformed image. The rest of frequencies are zeroed.

Sample usage:

 // create complex image ComplexImage complexImage = ComplexImage.FromBitmap( image ); // do forward Fourier transformation complexImage.ForwardFourierTransform( ); // create filter FrequencyFilter filter = new FrequencyFilter( new IntRange( 20, 128 ) ); // apply filter filter.Apply( complexImage ); // do backward Fourier transformation complexImage.BackwardFourierTransform( ); // get complex image as bitmat Bitmap fourierImage = complexImage.ToBitmap( );
