Method Detail

init

@Cast(value="bool")
public boolean init(@ByVal
                                        opencv_core.Mat image,
                                        @Const @ByRef
                                        opencv_core.Rect2d boundingBox)

\brief Initialize the tracker with a known bounding box that surrounded the target

Parameters:

image - The initial frame

boundingBox - The initial bounding box

Returns:

True if initialization went succesfully, false otherwise

init

@Cast(value="bool")
public boolean init(@ByVal
                                        opencv_core.UMat image,
                                        @Const @ByRef
                                        opencv_core.Rect2d boundingBox)

init

@Cast(value="bool")
public boolean init(@ByVal
                                        opencv_core.GpuMat image,
                                        @Const @ByRef
                                        opencv_core.Rect2d boundingBox)

update

@Cast(value="bool")
public boolean update(@ByVal
                                          opencv_core.Mat image,
                                          @ByRef
                                          opencv_core.Rect2d boundingBox)

\brief Update the tracker, find the new most likely bounding box for the target

Parameters:

image - The current frame

boundingBox - The bounding box that represent the new target location, if true was returned, not modified otherwise

Returns:

True means that target was located and false means that tracker cannot locate target in current frame. Note, that latter *does not* imply that tracker has failed, maybe target is indeed missing from the frame (say, out of sight)
