This is my "faces" Java applet (version of May 1, 2008). An explanation is below.

[Oops, your browser will not display java applets.]

This applet allows the user to draw an image of their choice, and then have the computer attempt to find either "faces" (i.e., two eyes and a nose), or "blobs" (i.e., simple oval shapes) of concentrated dots on the image. An explanation of the controls is as follows:

For now the Monte Carlo algorithm is very basic, but I plan to improve and expand it in the months ahead. I also plan to allow for importing external images (e.g. photographs) rather than just drawing them.

Note that the algorithm does not "cheat" by making use of the order in which the dots were created, nor which dots were created by the user and which ones at random. Rather, it makes use of the final image array and nothing more.

My interest in computer vision is quite recent, and was inspired partially by a talk by Yali Amit and meeting Sven Dickinson. I still have lots to learn, so hopefully my algorithms will improve with time.
