|
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.
(Defined by ExtensionMethods.) |
RemarksThe filter performs filtering of blobs by their size in the specified source image - all blobs, which are smaller or bigger then specified limits, are removed from the image.
 Note |
|---|
| The image processing filter treats all none black pixels as objects' pixels and all black pixel as background. |
The filter accepts 8 bpp grayscale images and 24/32 color images for processing.
Sample usage:
// create filter BlobsFiltering filter = new BlobsFiltering( ); // configure filter filter.CoupledSizeFiltering = true; filter.MinWidth = 70; filter.MinHeight = 70; // apply the filter filter.ApplyInPlace( image );
