AVL.ExtractBlobs_Intensity

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
inImageAvlNet.ImageImage from which blobs are extracted.
inRoiAvlNet.RegionRange of pixels to be processed. Default value: atl::NIL, or null.
inThresholdParamsAvlNet.IntensityThresholdParamsParameters for thresholding an image.
inRegionProcessingParamsAvlNet.RegionProcessingParamsParameters for opening and closing of a region.
inBlobSplittingParamsAvlNet.BlobSplittingParamsParameters for splitting region into blobs.
outBlobsAvlNet.Region[]Blobs extracted from the input image.
diagBlobAreasint[]Areas of extracted blobs.
diagBaseRegionAvlNet.RegionRegion 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

Examples

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