Cv2ConnectedComponentsWithAlgorithm Method

Computes the connected components labeled image of boolean image. 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 (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 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.
