![]() | ApplyInPlace(BitmapData) |
Apply filter to an image.
(Inherited from BaseUsingCopyPartialFilter.) |
![]() | ApplyInPlace(UnmanagedImage) |
Apply filter to an unmanaged image.
(Inherited from BaseUsingCopyPartialFilter.) |
![]() | ApplyInPlace(Bitmap, Rectangle) |
Apply filter to an image or its part.
(Inherited from BaseUsingCopyPartialFilter.) |
![]() | ApplyInPlace(BitmapData, Rectangle) |
Apply filter to an image or its part.
(Inherited from BaseUsingCopyPartialFilter.) |

(Inherited from BaseUsingCopyPartialFilter.) |
![]() | Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | GetHashCode | Serves as the default hash function. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | ProcessFilter |
Process the filter on the specified image.
(Overrides BaseUsingCopyPartialFilterProcessFilter(UnmanagedImage, UnmanagedImage, Rectangle).) |
![]() | ToString | Returns a string that represents the current object. (Inherited from Object.) |
Name | Description | |
---|---|---|
![]() | HasMethod |
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.) |
![]() | IsEqual |
Compares two objects for equality, performing an elementwise
comparison if the elements are vectors or matrices.
(Defined by Matrix.) |
![]() | To(Type) | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.
(Defined by ExtensionMethods.) |
![]() | ToT | Overloaded.
Converts an object into another type, irrespective of whether
the conversion can be done at compile time or not. This can be
used to convert generic types to numeric types during runtime.

The filter represents an optimized version of Dilation filter, which is aimed for binary images (containing black and white pixels) processed with 3x3 structuring element. This makes this filter ideal for growing objects in binary images – it puts white pixel to the destination image in the case if there is at least one white neighbouring pixel in the source image.
See Dilation filter, which represents generic version of dilation filter supporting custom structuring elements and wider range of image formats.
The filter accepts 8 bpp grayscale (binary) images for processing.
// Let's start with one of the default // color test images in the framework: var test = new TestImages(basePath); // Let's get Lena's picture Bitmap bmp = test["lena.bmp"]; // And transform it to a binary mask // using Niblack's threshold class var niblack = new NiblackThreshold(); Bitmap binary = niblack.Apply(bmp); // The result can be seen below: // ImageBox.Show(binary); // Now, let's finally apply the dilation // filter to the binarized image below: var dil3x3 = new BinaryDilation3x3(); Bitmap result = dil3x3.Apply(binary); // The result can be seen below: // ImageBox.Show(result);
