Currently I display the DB information on the web using asp file and a table . " We hope to be able to use speech recognition and a cross-lingual information retrieval technique to both speed up the annotation so it will be easier for the skilled translators to annotate and also to , at some point , make it possible for people to be able to search these data collections directly without the need of human annotation at all , " said Byrne . Many of the underlying technologies for the mission have been demonstrated including optical flow for terrain following , stabilization using cheap optical sensors and compassing using sun position and the polarization pattern in the sky . Using edge detection and a feedback loop , the model detects the lane markers and eliminates large variations in lane marker locations , which improves estimation accuracy .
