Parameters

Name Type Range Default Description
inImageFilNet.ImageImage from which blobs are extracted.
inStdDevfloat<0.0f, INF>3.0fSmoothing standard deviation for the smaller Gaussian kernel. Default value: 3.0f.
inStdDevRatiofloat<1.0f, INF>1.6fDefines how many times larger is the second Gaussian kernel. Default value: 1.6f.
inKernelRelativeSizefloat<0.0f, 3.0f>3.0fA multiple of the standard deviation determining the size of the Gaussian kernel. Default value: 3.0f.
inThresholdParamsFilNet.IntensityThresholdParamsParameters for thresholding an image.
inRegionProcessingParamsFilNet.RegionProcessingParamsParameters for opening and closing of a region.
inBlobSplittingParamsFilNet.BlobSplittingParamsParameters for splitting region into blobs.
outBlobsSystem.Collections.Generic.IList<FilNet.Region>Blobs extracted from the input image.
diagBlobAreasSystem.Collections.Generic.IList<int>Areas of extracted blobs.
diagBaseRegionFilNet.RegionRegion of pixels right after thresholding.

Description

This filter can be used to quickly segment an image by thresholding Difference of Gaussians. It performs a series of operations on inImage:

Examples

ExtractBlobs_DoG performed on the sample image with inStdDev = 6.0 and inThresholdParams.MaxIntensity = -4.0.
