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++

[OperationContractAttribute("IntensityDetect")] 
[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,  
   Action="",  
   Name="",  
   Namespace="",  
   ProtectionLevel=ProtectionLevel.None,  
   HasProtectionLevel=false)] 
Leadtools.Services.Imageprocessing.Datacontracts.CommandResponse IntensityDetect(  
   Leadtools.Services.Imageprocessing.Datacontracts.IntensityDetectRequest request 
)

[OperationContractAttribute("IntensityDetect")] 
[FaultContractAttribute(DetailType=Leadtools.Services.Raster.FaultContracts.RasterFault,  
   Action="",  
   Name="",  
   Namespace="",  
   ProtectionLevel=ProtectionLevel.None,  
   HasProtectionLevel=false)] 
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.
