KNearestNeighborMatching Class |
Nearest neighbor feature point matching algorithm.
Inheritance HierarchyNamespace: Accord.Imaging
Assembly: Accord.Vision (in Accord.Vision.dll) Version: 3.8.0
SyntaxThe KNearestNeighborMatching type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | KNearestNeighborMatching(Int32) |
Constructs a new
K-Nearest Neighbors matching algorithm.
|
| KNearestNeighborMatching(Int32, IDistanceDouble) |
Constructs a new
K-Nearest Neighbors matching algorithm.
|
Properties| Name | Description | |
|---|---|---|
 | Distance |
Gets or sets the distance function used
as a distance metric between data points.
(Inherited from KNearestNeighborMatchingT.) |
| K |
Gets or sets the number k of nearest neighbors.
(Inherited from KNearestNeighborMatchingT.) |
| Threshold |
Gets or sets a minimum relevance threshold
used to find matching pairs. Default is 0.
(Inherited from KNearestNeighborMatchingT.) |
Methods| Name | Description | |
|---|---|---|
 | CreateNeighbors |
Creates a nearest neighbor algorithm with the feature points as
inputs and their respective indices a the corresponding output.
(Overrides KNearestNeighborMatchingTCreateNeighbors(T).) |
| 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.) |
| Match(IFeaturePointT, IFeaturePointT) |
Matches two sets of feature points.
(Inherited from KNearestNeighborMatchingT.) |
| Match(IEnumerableIFeaturePointT, IEnumerableIFeaturePointT) |
Matches two sets of feature points.
(Inherited from KNearestNeighborMatchingT.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| 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.
