	WHAT'S YOUR ENGINEERING QUOTIENT?
•Homerun? Problem 8—You work for a robotics company and, for a demo project, you are helping design a robotic skeet shooter. All that remains is developing a tracking algorithm. You are receiving a video image with sufficient frame speed to track the target. You need an algorithm to help guess where the target will be in successive video frames. What would you suggest? Answer: After each frame is captured, scan the perimeter of the target. Using the perimeter points, you can calculate x and y coordinates for the center of gravity of the target. Using the center of gravity coordinate from the current frame and the previous frame, you can determine a direction and speed of travel to compute the expected location for the next frame. 8-99 For questions or comments about Test Your EQ, e-mail eq@circuitcellar.com.
