C# Class Accord.Imaging.Filters.Dilatation

Dilatation operator from Mathematical Morphology.

The filter assigns maximum value of surrounding pixels to each pixel of the result image. Surrounding pixels, which should be processed, are specified by structuring element: 1 - to process the neighbor, -1 - to skip it.

The filter especially useful for binary image processing, where it allows to grow separate objects or join objects.

For processing image with 3x3 structuring element, there are different optimizations available, like Dilatation3x3 and BinaryDilatation3x3.

The filter accepts 8 and 16 bpp grayscale images and 24 and 48 bpp color images for processing.

Sample usage:

// create filter Dilatation filter = new Dilatation( ); // apply the filter filter.Apply( image );

Public Methods

Method	Description
Dilatation ( ) : System	Initializes a new instance of the Dilatation class. Initializes new instance of the Dilatation class using default structuring element - 3x3 structuring element with all elements equal to 1.
Dilatation ( short se ) : System	Initializes a new instance of the Dilatation class. Structuring elemement for the dilatation morphological operator must be square matrix with odd size in the range of [3, 99].

Protected Methods

Method	Description
ProcessFilter ( UnmanagedImage sourceData, UnmanagedImage destinationData, Rectangle rect ) : void	Process the filter on the specified image.
