CamGrab.java

/*
 * need to:
 * port findcenter to java
 * implement image savecenter
 * implement image findcenter
 * try savecenter/findcenter using edge detect instead
 * make image toolkit class: edge detect, blur, convert to grey
 * 
 * interface: swing (so don't have to compile/run red5 every time)
 * need 2-3 320x240 images, series of buttons
