The transmission of streaming data, because of its real-time nature, is subject to bandwidth constraints. We propose a MPEG-2 compliant decoder which uses data hiding to transmit additional data with no extra bandwidth while creating an almost imperceptible degradation of the picture. The additional data can be anything from subtitles to correction signals(More)
Digital watermarking is a very common technique used against illicit copying and distribution of copyright material. This paper presents improved methods for information hiding. We propose a new approach, based on the decorrelation property of the Karhunen-Loeve transform (KLT).
In a ubiquitous environment, intellignet functions are embedded in objects around the user, thus enabling him to create variuos functionalities by combining those objects. The collaborative robotic environments are a new approach to the coordination of multirobot systems which usually consist of numerous, relatively simple, small sized robots. The CORE-TX(More)
