Background Subtraction
======================
.. highlight:: cpp
gpu::VIBE_GPU
-------------
.. ocv:class:: gpu::VIBE_GPU
Class used for background/foreground segmentation. ::
class VIBE_GPU
{
public:
explicit VIBE_GPU(unsigned long rngSeed = 1234567);
void initialize(const GpuMat& firstFrame, Stream& stream = Stream::Null());
void operator()(const GpuMat& frame, GpuMat& fgmask, Stream& stream = Stream::Null());
void release();
...
};
The class discriminates between foreground and background pixels by building and maintaining a model of the background. Any pixel which does not fit this model is then deemed to be foreground. The class implements algorithm described in [VIBE2011]_.
gpu::VIBE_GPU::VIBE_GPU
-----------------------
The constructor.
.. ocv:function:: gpu::VIBE_GPU::VIBE_GPU(unsigned long rngSeed = 1234567)
:param rngSeed: Value used to initiate a random sequence.
Default constructor sets all parameters to default values.
gpu::VIBE_GPU::initialize
-------------------------
Initialize background model and allocates all inner buffers.
.. ocv:function:: void gpu::VIBE_GPU::initialize(const GpuMat& firstFrame, Stream& stream = Stream::Null())
:param firstFrame: First frame from video sequence.
:param stream: Stream for the asynchronous version.
gpu::VIBE_GPU::operator()
-------------------------
Updates the background model and returns the foreground mask
.. ocv:function:: void gpu::VIBE_GPU::operator()(const GpuMat& frame, GpuMat& fgmask, Stream& stream = Stream::Null())
:param frame: Next video frame.
:param fgmask: The output foreground mask as an 8-bit binary image.
:param stream: Stream for the asynchronous version.
gpu::VIBE_GPU::release
----------------------
Releases all inner buffer's memory.
.. ocv:function:: void gpu::VIBE_GPU::release()
