◆ 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,
int  t = 0,

void cv::stereo::starCensusTransform ( const Mat img1,
int  kernelSize,
Mat dist 
)

single image version of star kernel
