1) Press play to run with default threshold or... 2) Select a different threshold and press play. 3) Press play again after changing Overlay to "clear" mode.a Click space to show/hide threshold slider. Will pop bubbles only if the child bubbles are more different in colour than specified by the threshold slider. So places where all pixels are similar will be displayed as one large pixel. Places where pixels differ will be displayed as many small pixels. Toggle clear/overlay to determine whether larger bubbles are replaced by smaller ones or covered by them.
