By default, ``StereoConstantSpaceBP`` uses floating-point arithmetics and the ``CV_32FC1`` type for messages. But it can also use fixed-point arithmetics and the ``CV_16SC1`` message type for better perfomance. To avoid an overflow in this case, the parameters must satisfy the following requirement:
:param distance:The output single-row ``CV_32FC1`` matrix that contains the best distance for each query. If some query descriptors are masked out in ``maskCollection`` , it contains ``FLT_MAX``.
:param maskCollection:``GpuMat`` containing a set of masks. It can be obtained from ``std::vector<GpuMat>`` by ?? or it may contain a user-defined mask set. This is an empty matrix or one-row matrix where each element is a ``PtrStep`` that points to one mask.
:param maskCollection:``GpuMat`` containing a set of masks. It can be obtained from ``std::vector<GpuMat>`` by :cpp:func:`gpu::BruteForceMatcher_GPU::makeGpuCollection` or it may contain a user-defined mask set. This is an empty matrix or one-row matrix where each element is a ``PtrStep`` that points to one mask.
:param feature:Feature to be checked. See :cpp:class:`gpu::GpuFeature`.
