FrequencyFilterMaskCommand Constructor()

Summary

Initializes a new FrequencyFilterMaskCommand class object with default parameters.

Syntax

C++/CLI

Python

public FrequencyFilterMaskCommand()

public: 
FrequencyFilterMaskCommand();

__init__() # Default constructor

Example

Run the FrequencyFilterMaskCommand on an image.

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core; 
 
public void FrequencyFilterMaskConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\FourierTransform.jpg")); 
 
   // Prepare the command 
   // Resize the image to make sure the image's dimensions are power of two. 
   SizeCommand sizeCommand = new SizeCommand(256, 256, RasterSizeFlags.Bicubic); 
   sizeCommand.Run(image); 
 
   FourierTransformInformation ftArray = new FourierTransformInformation(image); 
   // Apply FFT. 
   FastFourierTransformCommand command = new FastFourierTransformCommand(ftArray, FastFourierTransformCommandFlags.FastFourierTransform | FastFourierTransformCommandFlags.Gray); 
   command.Run(image); 
 
   FrequencyFilterMaskCommand freqCommand = new FrequencyFilterMaskCommand(); 
   freqCommand.MaskImage = image; 
   freqCommand.FourierTransformInformation = ftArray; 
   freqCommand.OnOff = false; 
 
   FastFourierTransformCommand invCommand = new FastFourierTransformCommand(ftArray, FastFourierTransformCommandFlags.InverseFastFourierTransform | FastFourierTransformCommandFlags.Gray | FastFourierTransformCommandFlags.Scale | 
         FastFourierTransformCommandFlags.Both); 
   invCommand.Run(image); 
 
}
