2.  The idea is to use the head as a replacement to the paddle which bounces the ball to destroy “mines” over your head.

3.  Haar Like Features ◦ Encode the existence of oriented contrasts between regions in the image. A set of these features can be used to encode the contrasts exhibited by a human face and their spacial relationships.  Trained Cascade Classifier ◦ A classifier is trained with hundreds of positive samples of the same size and also negative samples. After trained a classifier can be applied to a region of a image to identify an object.

4.  No Intersection.... No Collision

5.  Intersection.... Possible Collision  Verify the opacity on both images for every point of the intersection

6.  If in both images the point is opaque, then there is a COLLISION!!!!

7. 

8.  Helmet ◦ Only bounce when direction has postive y-axis ◦ In greyed area just bounce the ball back upwards

9.  What is it? ◦ Simple and Fast Multimedia Library ◦ Open Source API written in C++ to manipulate graphics, sound, network, etc.  Why use it? ◦ Portable (Windows/Linux/MacOS) ◦ Object-Oriented alternative to SDL ◦ Easily integrable with other GUIs (Qt, MFC, wxWidgets, X11) ◦ Available in C++, C,.NET, Python, Ruby, D
