On orbit, three-axis stabilization for horizontal flight, kept the camera axis pointed earthward for image motion compensation while minimizing blur from pitch, roll and yaw using the pitch and roll gyros updated continuously using infrared horizon sensors for determining the vertical to less than 0.1 degree accuracy.
The model, based on the average head and facial feature measurements obtained from a selection of racially and ethnically diverse participants, determined the magnitude of the distortive effect by presenting the face as a collection of parallel planes perpendicular to the main camera axis. It calculated the changes to the ratio between the nose's breadth and the width between the two cheekbones at various camera distances.
