C# Class AForge.Imaging.Filters.BlobsFiltering

Blobs filtering by size.

The filter performs filtering of blobs by their size in the specified source image - all blobs, which are smaller or bigger then specified limits, are removed from the image.

The image processing filter treats all none black pixels as objects' pixels and all black pixel as background.

The filter accepts 8 bpp grayscale images and 24/32 color images for processing.

Sample usage:

 // create filter BlobsFiltering filter = new BlobsFiltering( ); // configure filter filter.CoupledSizeFiltering = true; filter.MinWidth  = 70; filter.MinHeight = 70; // apply the filter filter.ApplyInPlace( image );

Public Methods

Method	Description
BlobsFiltering ( ) : System	Initializes a new instance of the BlobsFiltering class.
BlobsFiltering ( IBlobsFilter blobsFilter ) : System	Initializes a new instance of the BlobsFiltering class.
BlobsFiltering ( int minWidth, int minHeight, int maxWidth, int maxHeight ) : System	Initializes a new instance of the BlobsFiltering class. This constructor creates an instance of BlobsFiltering class with CoupledSizeFiltering property set to false.
BlobsFiltering ( int minWidth, int minHeight, int maxWidth, int maxHeight, bool coupledSizeFiltering ) : System	Initializes a new instance of the BlobsFiltering class. For information about coupled filtering mode see documentation for BlobCounterBase.CoupledSizeFiltering property of BlobCounterBase class.

Protected Methods

Method	Description
