SyntaxThe MoravecCornersDetector type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | MoravecCornersDetector |
Initializes a new instance of the MoravecCornersDetector class.
|
| MoravecCornersDetector(Int32) |
Initializes a new instance of the MoravecCornersDetector class.
|
| MoravecCornersDetector(Int32, Int32) |
Initializes a new instance of the MoravecCornersDetector class.
|
Properties| Name | Description | |
|---|---|---|
 | NumberOfInputs |
Returns -1.
(Inherited from BaseFeatureExtractorTFeature.) |
| NumberOfOutputs |
Gets the dimensionality of the features generated by this extractor.
(Inherited from BaseFeatureExtractorTFeature.) |
| SupportedFormats |
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.) |
| Threshold |
Threshold value, which is used to filter out uninteresting points.
|
| WindowSize |
Window size used to determine if point is interesting, [3, 15].
|
Methods| Name | Description | |
|---|---|---|
| Clone |
Creates a new object that is a copy of the current instance.
(Inherited from BaseFeatureExtractorTFeature.) |
 | Clone(ISetPixelFormat) |
Creates a new object that is a copy of the current instance.
(Overrides BaseFeatureExtractorTFeatureClone(ISetPixelFormat).) |
| Dispose |
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
(Inherited from BaseFeatureExtractorTFeature.) |
| Dispose(Boolean) |
Releases unmanaged and - optionally - managed resources.
(Inherited from BaseFeatureExtractorTFeature.) |
| 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.) |
| InnerProcess |
This method should be implemented by inheriting classes to implement the
actual corners detection, transforming the input image into a list of points.
(Overrides BaseCornersDetectorInnerProcess(UnmanagedImage).) |
| InnerTransform |
This method should be implemented by inheriting classes to implement the
actual feature extraction, transforming the input image into a list of features.
(Inherited from BaseCornersDetector.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ProcessImage(Bitmap) |
Process image looking for corners.
(Inherited from BaseCornersDetector.) |
| ProcessImage(BitmapData) |
Process image looking for corners.
(Inherited from BaseCornersDetector.) |
| ProcessImage(UnmanagedImage) |
Process image looking for corners.
(Inherited from BaseCornersDetector.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Transform(Bitmap) |
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.) |
| Transform(Bitmap) |
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.) |
| Transform(UnmanagedImage) |
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.) |
| Transform(UnmanagedImage) |
Applies the transformation to an input, producing an associated output.
(Inherited from BaseFeatureExtractorTFeature.) |
| Transform(Bitmap, IEnumerableTFeature) |
Applies the transformation to a set of input vectors,
producing an associated set of output vectors.
(Inherited from BaseFeatureExtractorTFeature.) |
| Transform(UnmanagedImage, IEnumerableTFeature) |
Applies the transformation to a set of input vectors,
producing an associated set of output vectors.
(Inherited from BaseFeatureExtractorTFeature.) |
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 class implements Moravec corners detector. For information about algorithm's details its description should be studied.
 Note |
|---|
| Due to limitations of Moravec corners detector (anisotropic response, etc.) its usage is limited to certain cases only. |
The class processes only grayscale 8 bpp and color 24/32 bpp images.
Sample usage:
// create corner detector's instance MoravecCornersDetector mcd = new MoravecCornersDetector( ); // process image searching for corners List<IntPoint> corners = scd.ProcessImage( image ); // process points foreach ( IntPoint corner in corners ) { // ... }
