AutoBinaryCommand Class

Summary

Applies binary segmentation to the image using an automatically calculated threshold based on a two-peak method of statistical analysis of the histogram. This command is available in the Document/Medical Toolkits.

Syntax

Objective-C

C++

Java

public class AutoBinaryCommand : RasterCommand

Public Class AutoBinaryCommand  
   Inherits RasterCommand

@interface LTAutoBinaryCommand : LTRasterCommand

public class AutoBinaryCommand extends RasterCommand

public ref class AutoBinaryCommand : public RasterCommand

Remarks

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.

Example

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

using Leadtools.Codecs; 
using Leadtools.ImageProcessing.Color;

{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, @"ImageProcessingDemo\Beauty16.jpg")); 
 
   // Prepare the command 
   AutoBinaryCommand command = new AutoBinaryCommand(); 
   //Apply Auto Binary Segment. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
