Leadtools.Windows.Media.Effects.Core Namespace : MultiscaleEnhancementCommandBitmapEffect Class




Enhances an image’s contrast, edges, and density range for use in Computed Radiography (CR), in a way that all relevant image features are rendered with an appropriate level of visibility. This command is available in the Medical toolkits.

Syntax

Visual Basic (Declaration) 
Public Class MultiscaleEnhancementCommandBitmapEffect 
   Inherits RasterCommandBitmapEffect
Visual Basic (Usage)Copy Code
Dim instance As MultiscaleEnhancementCommandBitmapEffect
C# 
public class MultiscaleEnhancementCommandBitmapEffect : RasterCommandBitmapEffect
Managed Extensions for C++ 
public __gc class MultiscaleEnhancementCommandBitmapEffect : public RasterCommandBitmapEffect
C++/CLI 
public ref class MultiscaleEnhancementCommandBitmapEffect : public RasterCommandBitmapEffect

Example

Run the MultiscaleEnhancementCommandBitmapEffect on an image.

Remarks

  • The command wraps techniques of image enhancements, such as contrast enhancement, edge enhancement and latitude reduction, for Computed Radiography (CR).
  • In multi-scale enhancement, the image is decomposed into components or levels. Those components or levels that contain details will be enhanced separately from other components or levels.
  • This will improve the visualization for the subtle image features without the risk of losing information of other features.
  • To find the number of levels in any image follow this equation:
  • MaximumLevels = ceil( log( max(pimage->Width, pimage->Height)) / log(2));
  • The command will consider values larger than 10000 for contrast as 10000. If the user used a conttrast of 0, then image contrast will not be improved.
  • Best results are obtained if contrast is in the range of 15 ~ 30. The larger the value the stronger the enhancement will be. Any stronger enhancement than 30 will reveal noise and no new enhancement will be noticed.
  • The user can further enhance the image withT:Leadtools.Windows.Media.Effects.Core.MultiscaleEnhancementCommandBitmapEffectsFlagsEdgeEnhancement) and/or
  • latitude reduction T:Leadtools.Windows.Media.Effects.Core.MultiscaleEnhancementCommandBitmapEffectsFlags Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical:T:Leadtools.Wpf.Topics.RasterProDocMed% toolkits.
  • This command does not support 32-bit grayscale images.
