Given a binary image of $n$ pixels, assign integral
labels to all pixels so that any background pixel
has label $0$ and any two foreground pixels have
the same positive integral labels if and only if
they belong to the same connected components.
This problem is referred to as 'Connected Components
Labeling' and it is one of the most fundamental
problems in image processing and analysis.
This paper presents a new algorithmic framework
for the problem.
From an algorithmic point of view, the problem
can be solved in $O(n)$ time and $O(n)$ space. We propose new algorithms which use smaller work space without much sacrifice of the running time.
More exactly, assuming that an input binary image is given on a read-only array, our algorithm outputs correct labels in the raster order in
$O(n log n)$ time using only $O(sqrt{n})$ work space. Some applications of the algorithm are also given. |
