The CornerFeaturesDetector type exposes the following members.

Constructors
  NameDescription
Public methodCornerFeaturesDetector
Initializes a new instance of the CornerFeaturesDetector class.
Top
Properties
  NameDescription
Public propertyDetector
Gets the corners detector used to generate features.
Public propertyNumberOfInputs
Returns -1.
(Inherited from BaseFeatureExtractorTFeature.)
Public propertyNumberOfOutputs
Gets the dimensionality of the features generated by this extractor.
(Inherited from BaseFeatureExtractorTFeature.)
Public propertySupportedFormats
Gets the list of image pixel formats that are supported by this extractor. The extractor will check whether the pixel format of any provided images are in this list to determine whether the image can be processed or not.
(Inherited from BaseFeatureExtractorTFeature.)

Methods
  NameDescription
Public methodClone
Creates a new object that is a copy of the current instance.
(Inherited from BaseFeatureExtractorTFeature.)
Protected methodClone(ISetPixelFormat)
Creates a new object that is a copy of the current instance.
(Overrides BaseFeatureExtractorTFeatureClone(ISetPixelFormat).)
Public methodDispose
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
(Inherited from BaseFeatureExtractorTFeature.)
Protected methodDispose(Boolean)
Releases unmanaged and - optionally - managed resources.
(Overrides BaseFeatureExtractorTFeatureDispose(Boolean).)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodInnerTransform
This method should be implemented by inheriting classes to implement the actual corners detection, transforming the input image into a list of points.
(Overrides BaseFeatureExtractorTFeatureInnerTransform(UnmanagedImage).)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodProcessImage(Bitmap) Obsolete.
Obsolete. Please use the Transform(Bitmap) method instead.
(Inherited from BaseSparseFeatureExtractorTPoint.)
Public methodProcessImage(BitmapData) Obsolete.
Obsolete. Please use the Transform(Bitmap) method instead.
(Inherited from BaseSparseFeatureExtractorTPoint.)
Public methodProcessImage(UnmanagedImage) Obsolete.
Obsolete. Please use the Transform(Bitmap) method instead.
(Inherited from BaseSparseFeatureExtractorTPoint.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodTransform(Bitmap)
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.)
Public methodTransform(Bitmap)
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.)
Public methodTransform(UnmanagedImage)
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.)
Public methodTransform(UnmanagedImage)
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.)
Public methodTransform(Bitmap, IEnumerableTFeature)
Applies the transformation to a set of input vectors, producing an associated set of output vectors.
(Inherited from BaseFeatureExtractorTFeature.)
Public methodTransform(UnmanagedImage, IEnumerableTFeature)
Applies the transformation to a set of input vectors, producing an associated set of output vectors.
(Inherited from BaseFeatureExtractorTFeature.)

Extension Methods
  NameDescription
Public Extension MethodHasMethod
Checks whether an object implements a method with the given name.
(Defined by ExtensionMethods.)
Public Extension MethodIsEqual
Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices.
(Defined by Matrix.)
Public Extension MethodTo(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.)
Public Extension MethodToTOverloaded.
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.)

Remarks
This class can be used as an adapter for classes implementing AForge.NET's ICornersDetector interface, so they can be used where an IImageFeatureExtractorTFeature is needed.
Examples
