Member Function Documentation

◆ compute() [1/2]

virtual void cv::cuda::StereoSGM::compute ( InputArray  left,
InputArray  right,
OutputArray  disparity 
)
pure virtual

Computes disparity map for the specified stereo pair.

Parameters
leftLeft 8-bit or 16-bit unsigned single-channel image.
rightRight image of the same size and the same type as the left one.
disparityOutput disparity map. It has the same size as the input images. StereoSGM computes 16-bit fixed-point disparity map (where each disparity value has 4 fractional bits).

Implements cv::StereoMatcher.

◆ compute() [2/2]

virtual void cv::cuda::StereoSGM::compute ( InputArray  left,
InputArray  right,
OutputArray  disparity,
Stream stream 
)
pure virtual

Computes disparity map with specified CUDA Stream.
