public class AutoBinaryCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class AutoBinaryCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As AutoBinaryCommand

public sealed class AutoBinaryCommand : Leadtools.ImageProcessing.IRasterCommand

@interface LTAutoBinaryCommand : LTRasterCommand

public class AutoBinaryCommand extends RasterCommand

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

The image is transformed into a binary image using a threshold calculated automatically based on statistical features of the image. Best results are obtained with grayscale images.
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.
If the image has a region, the effect will be applied on the region only.
This command does not support signed data images.
This command does not support 32-bit grayscale images.

Use the AutoBinaryCommand when you simply want to apply binary segmentation to the bitmap using an automatically calculated threshold based on a two-peak method of statistical analysis on its histogram. Use the DynamicBinaryCommand to convert an image into a black and white image without changing its bits per pixel. Use the AutoBinarizeCommand if you want:

Automatic pre-processing
Pre-processing to include background elimination
Pre-processing to include color leveling
To perform automatic, percentile or median thresholding
To manually specify a threshold value

For more information, refer to Processing an Image.
For more information, refer to Removing Noise.

Run the AutoBinaryCommand on an image and apply automatic binary segmentation on it.
