A novel closed contour extractor, principle and algorithm

The contour extraction is one of the most important steps in digital image processing. But the extracted contours with conventional algorithms are not always closed and continuous. They have also bifurcated segments. The needed computing time is intensive. In this paper, a novel algorithm called OCE (object-oriented contour extraction) has been proposed, which ensures a closure of all extracted contours, enables a parallel implementation in real-time and suppresses noise
