Need Help - Object Tracking

Dear All,

I need help with my coding. Im using Altera DE2 board and a Terasic TRDB-D5M camera. I need to make an object tracking device. Basically the camera will capture video and the DE2 board will process the video and will detect a red ball and then will control 2 servo motor to follow the ball. The problem is, I could not get any display on the VGA after I insert the detectRed module. If I use the basic D5M module provided with the camera, its operate perfectly. Really need help. Thank you.
