good day. i hope i put this topic on the right place. anybody here knows about how this algorithm works? i've seen it's application on an applet and it basically just follows the boundaries or the edges of a certain input image. i want to know how this algorithm works and where can i start in applying it to java programs.

thank you in advance.

A quick search for "boundary following algorithm" finds no particular algorithm; do you mean edge detection in general? If so, I'd start with the Sobel operator for which numerous example codes in Java float around the web, like this one that includes a demo applet.
