MinimumInput Property

Summary

Gets or sets the value that specifies which values are to be considered to be shadows.

Syntax

C++/CLI

Python

public int MinimumInput { get; set; }

public: 
property int MinimumInput { 
   int get(); 
   void set (    int ); 
}

MinimumInput # get and set (KaufmannRegionCommand)

Property Value

An integer which specifies which values are to be considered to be shadows. Valid values range from 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit images.

Remarks

This value is used internally to darken the shadows to make region selection easier.

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()); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS23\Resources\Images";
