Constructors| Name | Description | |
|---|---|---|
 | TopHat |
Initializes a new instance of the TopHat class.
|
| TopHat(Int16) |
Initializes a new instance of the TopHat class.

Properties| Name | Description | |
|---|---|---|
 | FormatTranslations |
Format translations dictionary.
(Overrides BaseInPlaceFilterFormatTranslations.) |
Methods| Name | Description | |
|---|---|---|
| Apply(Bitmap) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| Apply(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| Apply(UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseInPlaceFilter.) |
| Apply(UnmanagedImage, UnmanagedImage) |
Apply filter to an image in unmanaged memory.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(Bitmap) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(BitmapData) |
Apply filter to an image.
(Inherited from BaseInPlaceFilter.) |
| ApplyInPlace(UnmanagedImage) |
Apply filter to an unmanaged image.
(Inherited from BaseInPlaceFilter.) |
| 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 BaseInPlaceFilterProcessFilter(UnmanagedImage).) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
Extension Methods| 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.

RemarksTop-hat morphological operator subtracts result of morphological opening on the input image from the input image itself.
Applied to binary image, the filter allows to get all those object (their parts) which were removed by opening filter, but never restored.
The filter accepts 8 and 16 bpp grayscale images and 24 and 48 bpp color images for processing.
Sample usage:
// create filter TopHat filter = new TopHat( ); // apply the filter filter.Apply( image );
Initial image:
Result image:
