TrackerTLD Class

TLD is a novel tracking framework that explicitly decomposes the long-term tracking task into tracking, learning and detection. The tracker follows the object from frame to frame.The detector localizes all appearances that have been observed so far and corrects the tracker if necessary.The learning estimates detector’s errors and updates it to avoid these errors in the future.The implementation is based on @cite TLD . The Median Flow algorithm (see cv::TrackerMedianFlow) was chosen as a tracking component in this implementation, following authors. Tracker is supposed to be able to handle rapid motions, partial occlusions, object absence etc.

Properties
  NameDescription
Protected propertyAllocatedMemory
Gets or sets a memory address allocated by AllocMemory.
(Inherited from DisposableObject.)
Protected propertyAllocatedMemorySize
Gets or sets the byte length of the allocated memory
(Inherited from DisposableObject.)
Public propertyCvPtr
Native pointer of OpenCV structure
(Inherited from DisposableCvObject.)

Gets or sets a handle which allocates using cvSetData.
(Inherited from DisposableObject.)
Public propertyEmpty
Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read
(Inherited from Algorithm.)

Methods
  NameDescription
Protected methodAllocGCHandle
Pins the object to be allocated by cvSetData.
(Inherited from DisposableObject.)
Protected methodAllocMemory
Allocates the specified size of memory.
(Inherited from DisposableObject.)
Public methodStatic memberCreate
Constructor
Public methodStatic memberCreate(TrackerTLDParams)
Constructor
Public methodDispose
Releases the resources
(Inherited from DisposableObject.)
Protected methodDispose(Boolean)
Releases the resources
(Inherited from DisposableObject.)
Protected methodDisposeManaged
Releases managed resources
(Inherited from Tracker.)
Protected methodDisposeUnmanaged
releases unmanaged resources
(Inherited from DisposableCvObject.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Destructor
(Inherited from DisposableObject.)
Public methodGetDefaultName
Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.
(Inherited from Algorithm.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodInit
Initialize the tracker with a know bounding box that surrounding the target
(Inherited from Tracker.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Protected methodNotifyMemoryPressure
Notifies the allocated size of memory.
(Inherited from DisposableObject.)
Public methodRead
Reads algorithm parameters from a file storage
(Inherited from Algorithm.)
Public methodSave
Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage fs).
(Inherited from Algorithm.)
Public methodThrowIfDisposed
If this object is disposed, then ObjectDisposedException is thrown.
(Inherited from DisposableObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
Public methodUpdate
Update the tracker, find the new most likely bounding box for the target
(Inherited from Tracker.)
Public methodWrite
Stores algorithm parameters in a file storage
(Inherited from Algorithm.)
