- 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.
