C# Класс AForge.Imaging.ComplexImage

Complex image.

The class is used to keep image represented in complex numbers sutable for Fourier transformations.

Sample usage:

// create complex image ComplexImage complexImage = ComplexImage.FromBitmap( image ); // do forward Fourier transformation complexImage.ForwardFourierTransform( ); // get complex image as bitmat Bitmap fourierImage = complexImage.ToBitmap( );

Initial image:

Fourier image:

Открытые методы

Метод Описание
BackwardFourierTransform ( ) : void

Applies backward fast Fourier transformation to the complex image.
Clone ( ) : object

Clone the complex image.
ForwardFourierTransform ( ) : void

Applies forward fast Fourier transformation to the complex image.
FromBitmap ( Bitmap image ) : ComplexImage

Create complex image from grayscale bitmap.
FromBitmap ( BitmapData imageData ) : ComplexImage

Create complex image from grayscale bitmap.
ToBitmap ( ) : Bitmap

Convert complex image to bitmap.

Защищенные методы

Метод Описание
ComplexImage ( int width, int height ) : System

Initializes a new instance of the ComplexImage class.

The constractor is protected, what makes it imposible to instantiate this class directly. To create an instance of this class FromBitmap(Bitmap) or FromBitmap(BitmapData) method should be used.
