| Cv2ConnectedComponentsWithStatsWithAlgorithm Method |
computes the connected components labeled image of boolean image and also produces a statistics output for each label.
image with 4 or 8 way connectivity - returns N, the total number of labels[0, N - 1] where 0
represents the background label.ltype specifies the output label image type, an important
consideration based on the total number of labels or alternatively the total number of pixels in
the source image.ccltype specifies the connected components labeling algorithm to use, currently
Grana's (BBDT) and Wu's (SAUF) algorithms are supported, see the #ConnectedComponentsAlgorithmsTypes
for details.Note that SAUF algorithm forces a row major ordering of labels while BBDT does not.
This function uses parallel version of both Grana and Wu's algorithms (statistics included) if at least one allowed
parallel framework is enabled and if the rows of the image are at least twice the number returned by #getNumberOfCPUs.

Parameters
- image
- Type: OpenCvSharpInputArray
the 8-bit single-channel image to be labeled - labels
- Type: OpenCvSharpOutputArray
destination labeled image - stats
- Type: OpenCvSharpOutputArray
statistics output for each label, including the background label, see below for
available statistics.Statistics are accessed via stats(label, COLUMN) where COLUMN is one of #ConnectedComponentsTypes. The data type is CV_32S. - centroids
- Type: OpenCvSharpOutputArray
centroid output for each label, including the background label. Centroids are
accessed via centroids(label, 0) for x and centroids(label, 1) for y.The data type CV_64F. - connectivity
- Type: OpenCvSharpPixelConnectivity
8 or 4 for 8-way or 4-way connectivity respectively - ltype
- Type: OpenCvSharpMatType
output image label type. Currently CV_32S and CV_16U are supported. - ccltype
- Type: OpenCvSharpConnectedComponentsAlgorithmsTypes
connected components algorithm type.
