Summary

Initializes a new KaufmannRegionCommand class object with explicit parameters.

Syntax

C++/CLI

Python

public KaufmannRegionCommand( 
   int radius, 
   int minimumInput, 
   int maximumInput, 
   int regionThreshold, 
   LeadPoint regionStart, 
   bool removeHoles, 
   RasterRegionCombineMode combineMode 
)

public: 
KaufmannRegionCommand(  
   int radius, 
   int minimumInput, 
   int maximumInput, 
   int regionThreshold, 
   LeadPoint regionStart, 
   bool removeHoles, 
   RasterRegionCombineMode combineMode 
)

__init__(self,radius,minimumInput,maximumInput,regionThreshold,regionStart,removeHoles,combineMode) # Overloaded constructor

Parameters

radius
Value that indicates the size of the neighborhood used for blurring each pixel of the image.

minimumInput
Value that specifies the image's shadows to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

maximumInput
Value that specifies the image's highlights to be mapped. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

regionThreshold
Value that specifies the values that set the stopping point for the region.

regionStart
Value that indicates whether to remove all holes from the region that's created internally.

removeHoles
Value that indicates whether to remove all holes from the region that's created internally.

combineMode
Value that represent the action to take regarding the existing image region, if one is defined.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Core; 
 
public void KaufmannRegionCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "Image3.dcm")); 
 
   // Prepare the command 
   LeadPoint startPoint = new LeadPoint((image.Width / 2), (image.Height / 2)); 
 
   // apply the command in order to get the pixels count of the first region. 
   KaufmannRegionCommand KaufmannCommandInner = new KaufmannRegionCommand(); 
   KaufmannCommandInner.CombineMode = RasterRegionCombineMode.Set; 
   KaufmannCommandInner.MaximumInput = 110; 
   KaufmannCommandInner.MinimumInput = 54; 
   KaufmannCommandInner.Radius = 21; 
   KaufmannCommandInner.RegionStart = startPoint; 
   KaufmannCommandInner.RegionThreshold = 13; 
   KaufmannCommandInner.RemoveHoles = true; 
   KaufmannCommandInner.Run(image); 
 
   int firstPixelCount = KaufmannCommandInner.PixelsCount; 
 
   // apply the command once more. 
   KaufmannRegionCommand KaufmannCommandOuter = new KaufmannRegionCommand(29, 51, 229, 207, startPoint, true, RasterRegionCombineMode.Set); 
   KaufmannCommandOuter.Run(image); 
 
   int secondPixelCount = KaufmannCommandOuter.PixelsCount; 
 
   // print the ratio between the first and the second region. 
   double result = (firstPixelCount * 1.0 / secondPixelCount); 
   MessageBox.Show(result.ToString());
