Abstract

Burada, bir göstergede (örnegin bir video görüntüsünde) bulunan bir çok bit'li filigranin belirlenmesine iliskin bir yöntem ve düzenleme gösterilmektedir. Çok bit'li degerdeki her bit, göstergenin bünyesinde bulunan bir filigran alt modeliyle temsil edilir. Her bir alt modelin mevcudiyetinin bilinen sekilde (yani her bir bit'in belirlenmesiyle) tespit edilmesi yerine belirleme süreci su asamalari içermektedir; çok bit'li degerine bakilmaksizin göstergedeki bütün filigranin mevcudiyetinin belirlenmesi (24,23) ve alt modellerin mevcudiyetinin incelenecek çok bit'li degere ne ölçüde denk düstügünün belirlenmesi (25). Filigran halindeki göstergelerin güvenilirligi bu sekilde arttirilmaktadir.
