C# 클래스 AForge.Imaging.Filters.Closing

Closing operator from Mathematical Morphology.

Closing morphology operator equals to dilatation followed by erosion.

Applied to binary image, the filter may be used connect or fill objects. Since dilatation is used first, it may connect/fill object areas. Then erosion restores objects. But since dilatation may connect something before, erosion may not remove after that because of the formed connection.

See documentation to Erosion and Dilatation classes for more information and list of supported pixel formats.

Sample usage:

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

Initial image:

Result image:

메소드	설명
Apply ( Bitmap image ) : Bitmap	Apply filter to an image. The method keeps the source image unchanged and returns the result of image processing filter as new image.
Apply ( BitmapData imageData ) : Bitmap	Apply filter to an image. The filter accepts bitmap data as input and returns the result of image processing filter as new image. The source image data are kept unchanged.
Apply ( UnmanagedImage image ) : UnmanagedImage	Apply filter to an image in unmanaged memory. The method keeps the source image unchanged and returns the result of image processing filter as new image.
Apply ( UnmanagedImage sourceImage, UnmanagedImage destinationImage ) : void	Apply filter to an image in unmanaged memory. The method keeps the source image unchanged and puts result of image processing into destination image. The destination image must have the same width and height as source image. Also destination image must have pixel format, which is expected by particular filter (see FormatTranslations property for information about pixel format conversions).
ApplyInPlace ( Bitmap image ) : void	Apply filter to an image. The method applies the filter directly to the provided source image.
ApplyInPlace ( Bitmap image, Rectangle rect ) : void	Apply filter to an image or its part. The method applies the filter directly to the provided source image.
ApplyInPlace ( BitmapData imageData ) : void	Apply filter to an image. The method applies the filter directly to the provided source image.
ApplyInPlace ( BitmapData imageData, Rectangle rect ) : void	Apply filter to an image or its part. The method applies the filter directly to the provided source image.
ApplyInPlace ( UnmanagedImage image ) : void	Apply filter to an unmanaged image. The method applies the filter directly to the provided source unmanaged image.
ApplyInPlace ( UnmanagedImage image, Rectangle rect ) : void	Apply filter to an unmanaged image or its part. The method applies the filter directly to the provided source image.
Closing ( ) : System	Initializes a new instance of the Closing class. Initializes new instance of the Closing class using default structuring element for both Erosion and Dilatation classes - 3x3 structuring element with all elements equal to 1.
Closing ( short se ) : System	Initializes a new instance of the Closing class. See documentation to Erosion and Dilatation classes for information about structuring element constraints.
