 * How to interact: firstly, click mouse somewhere within the frame. Move move across the area of the frame to find your favorite brush size (the smaller, the sharper of my image).  
 * Leave mouse for a while, the more circles, the sharper of my image. 
 * Parameters used in sourcecode are referenced from my body weight, width and height 
 * on the day i handed in this work. The image is taken from my university id card.
