LEADTOOLS Image Processing (Leadtools.ImageProcessing.Color assembly)
LEAD Technologies, Inc

DynamicBinaryCommand Class

Example 





Members 
Converts an image into a black and white image without changing its bits per pixel by using a local threshold value for each pixel of the image. This function is useful for pre-processing images for the purpose of improving barcode recognition results. .NET support WinRT support Silverlight support
Object Model
DynamicBinaryCommand Class
Syntax
'Declaration
 
Public Class DynamicBinaryCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand 
'Usage
 
Dim instance As DynamicBinaryCommand
public sealed class DynamicBinaryCommand : Leadtools.ImageProcessing.IRasterCommand  
function Leadtools.ImageProcessing.Color.DynamicBinaryCommand()
public ref class DynamicBinaryCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand  
Remarks
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: For more information, refer to Introduction to Image Processing With LEADTOOLS.
