Constructor & Destructor Documentation

§ StereoBeliefPropagation() [1/2]

cv::gpu::StereoBeliefPropagation::StereoBeliefPropagation ( int  ndisp = DEFAULT_NDISP,
int  iters = DEFAULT_ITERS,
int  levels = DEFAULT_LEVELS,
int  msg_type = CV_32F 

the default constructor

§ StereoBeliefPropagation() [2/2]

cv::gpu::StereoBeliefPropagation::StereoBeliefPropagation ( int  ndisp,
int  iters,
int  levels,
float  max_data_term,
float  data_weight,
float  max_disc_term,
float  disc_single_jump,
int  msg_type = CV_32F 

the full constructor taking the number of disparities, number of BP iterations on each level, number of levels, truncation of data cost, data weight, truncation of discontinuity cost and discontinuity single jump DataTerm = data_weight * min(fabs(I2-I1), max_data_term) DiscTerm = min(disc_single_jump * fabs(f1-f2), max_disc_term) please see paper for more details

§ estimateRecommendedParams()

static void cv::gpu::StereoBeliefPropagation::estimateRecommendedParams ( int  width,
int  height,
int ndisp,
int iters,
int levels 

§ operator()() [1/2]

void cv::gpu::StereoBeliefPropagation::operator() ( const GpuMat left,
const GpuMat right,
GpuMat disparity,
Stream stream = Stream::Null() 

the stereo correspondence operator. Finds the disparity for the specified rectified stereo pair, if disparity is empty output type will be CV_16S else output type will be disparity.type().

§ operator()() [2/2]

void cv::gpu::StereoBeliefPropagation::operator() ( const GpuMat data,
GpuMat disparity,
Stream stream = Stream::Null()
