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%.LatitudeReduction)
  • The edge levels, edge coefficient, latitude levels and latitude coefficient values are available for advanced users. Using -1 would give the maximum enhancements.
