Segments an image into blobs by thresholding.
Namespace: | AvlNet |
---|---|
Assembly: | AVL.NET.dll |
Syntax
C++
C#
public static void ExtractBlobs_Intensity ( AvlNet.Image inImage, AvlNet.Region inRoi, AvlNet.IntensityThresholdParams inThresholdParams, AvlNet.RegionProcessingParams inRegionProcessingParams, AvlNet.BlobSplittingParams inBlobSplittingParams, out AvlNet.Region[] outBlobs, out int[] diagBlobAreas, out AvlNet.Region diagBaseRegion )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | AvlNet.Image | Image from which blobs are extracted. | ||
![]() | inRoi | AvlNet.Region | Range of pixels to be processed. Default value: atl::NIL, or null. | ||
![]() | inThresholdParams | AvlNet.IntensityThresholdParams | Parameters for thresholding an image. | ||
![]() | inRegionProcessingParams | AvlNet.RegionProcessingParams | Parameters for opening and closing of a region. | ||
![]() | inBlobSplittingParams | AvlNet.BlobSplittingParams | Parameters for splitting region into blobs. | ||
![]() | outBlobs | AvlNet.Region[] | Blobs extracted from the input image. | ||
![]() | diagBlobAreas | int[] | Areas of extracted blobs. | ||
![]() | diagBaseRegion | AvlNet.Region | Region of pixels right after thresholding. |
Description
This filter can be used to quickly segment an image. It performs a series of operations on inImage:
- image is thresholded by ThresholdToRegion using parameters from inThresholdParams
- resulting region is opened and then closed by OpenRegion and CloseRegion using parameters from inRegionProcessingParams
- resulting region is split into blobs by SplitRegionIntoBlobs using parameters from inBlobSplittingParams

ExtractBlobs_Intensity performed on the sample image with inThresholdParams.MaxIntensity = 84.0 and inRegionProcessingParams.ClosingRadius = 10.
