            changePrevMax = changeCurMin + (changeCurMax-changeCurMin)/2;
            changePrevMin=changePrevMax;

        }
        imageDepictor.setDepiction(resulTemp);
        return imageDepictor;
    }

the method says where movement went to, by comparing the bitmap it gets to the prev bitmap it got(in the previous call).

implosion means the object shrunk(went far or got small in size)
