ShrinkWrapCommand Class

Summary

Performs automated segmentation of a rectangular or circular area in the specified image using the specified threshold.

Syntax

Objective-C

C++/CLI

Java

Python

public class ShrinkWrapCommand : RasterCommand

@interface LTShrinkWrapCommand : LTRasterCommand

public class ShrinkWrapCommand 
    extends RasterCommand

public ref class ShrinkWrapCommand : public RasterCommand

class ShrinkWrapCommand(RasterCommand):

Remarks

The result is applied to the image as a region. This function was designed specifically for CT/MRI images, to segment regions of cancer clusters.

Use MakeRegionEmpty to delete the resulting region.
The radius must not exceed the length of the image diagonal or the class will throw an Invalid Parameters exception and will not execute.
This command does not support 32-bit grayscale images.
This command supports signed/unsigned images.
