| Member | Description | |
|---|---|---|
| SURFTracker(array<SURFFeature>[]()[]) |
Create a SURF tracker, where SURF is matched with k-d Tree
|
| SURFTracker(array<SURFFeature>[]()[], Int32, Double, Double) |
Create a SURF tracker, where SURF is matched with k-d Tree
|
| CamShiftTrack(array<SURFFeature>[]()[], MCvBox2D, Image<(Of <(Gray, Single>)>)) |
Use camshift to track the feature
|
| Detect(array<SURFFeature>[]()[], Double) |
Detect the if the model features exist in the observed features. If true, an homography matrix is returned, otherwise, null is returned.
|
| Dispose()()() |
The dispose function that implements IDisposable interface
(Inherited from DisposableObject.) |
 | DisposeObject()()() |
Release unmanaged memory
(Overrides DisposableObject..::.DisposeObject()()().) |
| Equals(Object) | (Inherited from Object.) |
| Finalize()()() |
Destructor
(Inherited from DisposableObject.) |
| GetHashCode()()() | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetHomographyMatrixFromMatchedFeatures(array<SURFTracker..::.MatchedSURFFeature>[]()[]) |
Recover the homography matrix using RANDSAC. If the matrix cannot be recovered, null is returned.
|
| GetType()()() | Gets the Type of the current instance. (Inherited from Object.) |
| MatchFeature(array<SURFFeature>[]()[], Int32, Int32) |
Match the SURF feature from the observed image to the features from the model image
|
| MemberwiseClone()()() | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReleaseManagedResources()()() |
Release the memory assocaited with this SURF Tracker
(Overrides DisposableObject..::.ReleaseManagedResources()()().) |
| SortMatchedSURFFeatures(array<SURFTracker..::.MatchedSURFFeature>[]()[]) |
Sorted the matched SURF feature, such that a matchedFeature with smaller distance has a lower index
|
| ToString()()() | (Inherited from Object.) |
| VoteForSizeAndOrientation(array<SURFTracker..::.MatchedSURFFeature>[]()[], Double, Int32) |
Eliminate the matched features whose scale and rotation do not aggree with the majority's scale and rotation.
|
| VoteForUniqueness(array<SURFTracker..::.MatchedSURFFeature>[]()[], Double) |
Filter the matched Features, such that if a match is not unique, it is rejected.
