I have load the image of the world (background) into void setup, also in the 2nd screen shot i had set the size of the background to exactly the same size as the canvas.
At this step at this i am scaling the background in-order for it to fill the canvas without having any gaps.
for the stroke weight/ which was the to enhance the out line on the rectangle so the it is more visible for my audience/user. I also made the color in the box transparent so the user can also have a vision of on the map of the country that they are hovering over.
This is what the box looks like that represents the audience in the digital world. As you can see that it is transparent and as it hoovers around each country it gives you clearer idea of where roughly you are and it looks more refined.
I choose to use the face tracking because i was having slight bugging issues with the other cascade for example the nose, eyes and full-body. the nose tracking was too small and would not detect the nose if it is more than 2 meters away, and was picking up random object around the area.
