| Cv2ConnectedComponents Method (InputArray, OutputArray, PixelConnectivity) |
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.
