This is my "ovalblobs" Java applet (January 23, 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 oval-shaped "blobs" of concentrated dots on the image. An explanation of the controls is as follows:

Note that the algorithm does not "cheat" by making use of the order in which the dots were created, or which dots were created by the user and which ones at random. Rather, it makes use of the final image array and nothing more.

This applet is similar to the previous version, but it allows for non-circular blobs, does more efficient searching, and works more smoothly in a number of ways. I still plan to improve and expand the Monte Carlo algorithms in the months ahead, including searching for faces rather than just blobs. I also plan to allow for importing external images (e.g. photographs) rather than just drawing them.
