Furthermore, it describes an application prototype using this feature for face-tracking and its extensive evaluation. The main achievement of this thesis is the development of an alternative, simple and robust basis for face-tracking solutions and other image processing purposes. This novel method allows the encoding of local, structural features that are recognizeable in gray-scale images as so-called Binary Direction Vectors (BDVs). This representation of structural information is successfully combined with the existing tracking algorithm \"OpenCV CAMSHIFT Tracker\", to demonstrate the simple handling of BDVs. The tracking precision of the CAMSHIFT\/BDV combination is increased by modifying the statistical analysis that is used by the tracking algorithm. The supremacy of the modified version of the tracking algorithm over the original version is proved with an extensive empirical evaluation. These evaluation series also demonstrate how tracking systems can be compared in a precise and scientifically founded way.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Hajo Hoffmann\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 3836499320\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783836499323\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag Dr. Mueller E.K.\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 05\/09\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 104\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.33lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.22d","brand":"Hajo Hoffmann","offers":[{"title":"Paperback","offer_id":48446428086527,"sku":"9783836499323","price":52.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_8c98c305-3e65-4c49-bb8e-54201d6756f5.jpg?v=1777224562","url":"https:\/\/www.whiterainbookhouse.com\/products\/tracking-faces-in-grayscale-video-hajo-hoffmann-9783836499323","provider":"WR Book House","version":"1.0","type":"link"}
