A Linear Time Component Labeling Algorithm Using Contour Tracing Technique

quotA linear-time component-labeling algorithm using contour tracing techniquequot by Fu Chang, Chun-Jen Chen, and Chi-Jen Lu. Example The test directory contains the source code of a small program that generates an image of the label buffer as long as a JSON file and a GNUplot data file containing the set of extracted contours.

A new method for finding connected components frombinary images is presented in this article. The main stepof this method is to use a contour tracing technique todetect component contours and also to fill in interior areas.All the component points are traced by this algorithmin a single pass and are assigned either a new label orthe same label as their neighboring pixels.

A new linear-time algorithm is presented in this paper that simultaneously labels connected components to be referred to merely as components in this paper and their contours in binary images. The main step of this algorithm is to use a contour tracing technique to detect the external contour and possible internal contours of each component

The main step of this algorithm is to use a contour tracing technique to 13 detect the external contour and possible internal contours of each component, and also to 14 identify and label the interior area of each component. Labeling is done in a single pass over 15 the image, while contour points are revisited more than once, but no more than

To get the components and contours of the hand in the binary image region a linear-time component-labeling algorithm using contour tracing is used Chang and Chen, 2003. The resulting outer

Our algorithm not only labels components but also ex- tracts component contours and sequential orders of contour points, which can be use- ful for many applications. Keywords component-labeling algorithm, contour tracing, linear-time algorithm. 1. Introduction. Researchers often face the need to detect and classify objects in images.

More and more real-time applications need more efficient labeling algorithm. A new component-labeling method RCL Run and Contour based Labeling algorithm is presented in this paper. This method adopts run technique, contour tracing technique and bit operation. These technologies eliminate completely the dependency of neighbor pixels' information. Experiment on various types of images shows
