Function Documentation

◆ censusTransform() [1/2]

void cv::stereo::censusTransform ( const Mat & image1,
const Mat & image2,
int kernelSize,
Mat & dist1,
Mat & dist2,
const int type )

Two variations of census applied on input images Implementation of a census transform which is taking into account just the some pixels from the census kernel thus allowing for larger block sizes

◆ censusTransform() [2/2]

void cv::stereo::censusTransform ( const Mat & image1,
int kernelSize,
Mat & dist1,
const int type )

single image census transform

◆ modifiedCensusTransform() [1/2]

void cv::stereo::modifiedCensusTransform ( const Mat & img1,
const Mat & img2,
int kernelSize,
Mat & dist1,
Mat & dist2,
const int type,
int t = 0,
const Mat & integralImage1 = Mat(),
const Mat & integralImage2 = Mat() )

STANDARD_MCT - Modified census which is memorizing for each pixel 2 bits and includes a tolerance to the pixel comparison MCT_MEAN_VARIATION - Implementation of a modified census transform which is also taking into account the variation to the mean of the window not just the center pixel

◆ modifiedCensusTransform() [2/2]

void cv::stereo::modifiedCensusTransform ( const Mat & img1,
int kernelSize,
Mat & dist,
const int type,
