Syntax

public static void ExtractBlobs_Dynamic ( FilNet.Image inImage, NullableRef<FilNet.Region> inRoi, FilNet.DynamicThresholdParams inThresholdParams, FilNet.RegionProcessingParams inRegionProcessingParams, FilNet.BlobSplittingParams inBlobSplittingParams, IList<FilNet.Region> outBlobs, IList<int> diagBlobAreas, FilNet.Region diagBaseRegion )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
![]() | inImage | FilNet.Image | Image from which blobs are extracted. | ||
![]() | inRoi | FilNet.NullableRef<FilNet.Region> | Range of pixels to be processed. Default value: ftl::NIL. | ||
![]() | inThresholdParams | FilNet.DynamicThresholdParams | Parameters for dynamic thresholding. | ||
![]() | inRegionProcessingParams | FilNet.RegionProcessingParams | Parameters for opening and closing of a region. | ||
![]() | inBlobSplittingParams | FilNet.BlobSplittingParams | Parameters for splitting region into blobs. | ||
![]() | outBlobs | System.Collections.Generic.IList<FilNet.Region> | Blobs extracted from the input image. | ||
![]() | diagBlobAreas | System.Collections.Generic.IList<int> | Areas of extracted blobs. | ||
![]() | diagBaseRegion | FilNet.Region | Region of pixels right after thresholding. |
Description
This filter can be used to quickly segment an image with uneven illumination. It performs a series of operations on inImage:
- image is thresholded by ThresholdToRegion_Dynamic 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
