WebYou input an image. The application performs edge detection and converts detected edges to lines. A sub-pixel edge detection algorithm [1] is used in this step. The application makes lines into an one-liner line. The details of this step can be found in the source code. The application draws the one-liner line using orbiting circles. http://bigwww.epfl.ch/demo/subpixeledge/start.php
