'Declaration
 
Public Class EdgeDetectStatisticalCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As EdgeDetectStatisticalCommand

public sealed class EdgeDetectStatisticalCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Effects.EdgeDetectStatisticalCommand()

public ref class EdgeDetectStatisticalCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

The edges are detected by applying a statistical filter that analyzes the variations of colors in all directions around each pixel.
This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support 32-bit grayscale images.

For more information, refer to Detecting and Enhancing Edges and Lines.
