Apply filter to an image.
(Inherited from BaseUsingCopyPartialFilter.) |
| ApplyInPlace(BitmapData) |
Apply filter to an image.
(Inherited from BaseUsingCopyPartialFilter.) |
| ApplyInPlace(UnmanagedImage) |
Apply filter to an unmanaged image.
(Inherited from BaseUsingCopyPartialFilter.) |

(Inherited from BaseUsingCopyPartialFilter.) |
| ApplyInPlace(UnmanagedImage, Rectangle) |
Apply filter to an unmanaged image or its part.
(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.) |
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.
(Defined by ExtensionMethods.) |
RemarksThe filter finds objects' edges by calculating maximum difference between pixels in 4 directions around the processing pixel.
Suppose 3x3 square element of the source image (x - is currently processed pixel):
P1 P2 P3 P8 x P4 P7 P6 P5
max( |P1-P5|, |P2-P6|, |P3-P7|, |P4-P8| )
The filter accepts 8 bpp grayscale images for processing.
Sample usage:
// create filter DifferenceEdgeDetector filter = new DifferenceEdgeDetector( ); // apply the filter filter.ApplyInPlace( image );
Initial image:
Result image:
