'Usage

Dim instance As MultiscaleEnhancementCommand

public sealed class MultiscaleEnhancementCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTMultiscaleEnhancementCommand : LTRasterCommand

public class MultiscaleEnhancementCommand extends RasterCommand

function Leadtools.ImageProcessing.Core.MultiscaleEnhancementCommand()

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

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 contrast of 0, then image contrast will not be improved.
Best results are obtained if contrast is in the range of 15 percent ~ 30 percent. The larger the value the stronger the enhancement will be. Any stronger enhancement than 30 percent will reveal noise and no new enhancement will be noticed.
The user can further enhance the image with:
- edge enhancements (use MultiscaleEnhancementCommandFlags.EdgeEnhancement) and/or
- latitude reduction (use MultiscaleEnhancementCommandFlags.LatitudeReduction)
The edge levels, edge coefficient, latitude levels and latitude coefficient values are available for advanced users. Using -1 would give the maximum enhancements.
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.
