IntensityDetect Method

Summary

Applies binary segmentation on an image by filtering a specific image to detect colors in a specific intensity range, in a specific color channel(s).

Syntax

C#
VB
C++
[OperationContractAttribute(Action="IntensityDetect", 
   AsyncPattern=false, 
   IsOneWay=false, 
   IsInitiating=true, 
   IsTerminating=false)]

) As Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse

Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse^ IntensityDetect(  
   Leadtools.Services.Imageprocessing.Datacontracts.IntensityDetectRequest^ request 
)  

Parameters

request
A System.Runtime.Serialization.DataContractAttribute containing the data that will be used in this IntensityDetect operation.

Return Value

A System.Runtime.Serialization.DataContractAttribute containing the modified image resulting from the IntensityDetect operation.

Remarks
  • The image is divided into two parts, inner and outer according to the values of the LowThreshold property and the HighThreshold property.
  • The operation can process 2 or more channels at a time by OR-ing two or more flags.
  • This operation 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.
