Summary
Erodes dark objects by the specified amount.
Syntax
C#
VB
Objective-C
C++
Java
public class MaximumCommand : RasterCommand 
Public Class MaximumCommand  
   Inherits RasterCommand 
@interface LTMaximumCommand : LTRasterCommand 
public class MaximumCommand extends RasterCommand 
public ref class MaximumCommand : public RasterCommand   
Remarks
  • This command can process the whole image or a region of the image.
  • The effect can be controlled by specifying the size of the neighborhood that is used for calculating each pixel value. For example, for 8x8, set Dimension property (or the dimension parameter of the Constructor) to 8. Each pixel is replaced with the maximum value of its neighborhood.
  • 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.
  • This command supports signed/unsigned data images.

For more information, refer to Removing Noise.

Example

Run the MaximumCommand on an image with a neighborhood Dimensions = 3x3 pixels.
