 component/pixel is stored in `labels(x, y)`. When labelType==#DIST_LABEL_CCOMP, the function
 automatically finds connected components of zero pixels in the input image and marks them with
-distinct labels. When labelType==#DIST_LABEL_CCOMP, the function scans through the input image and

 marks all the zero pixels with distinct labels.
 
 In this mode, the complexity is still linear. That is, the function provides a very fast way to
