Recently, many studies have reported that various kinds of real networks, such as WWW, the Internet, metabolic system , BtoB transactions and so on, have the scale-free properties in common. We focus on the network feeding Usenet news where a node represents a news server and a link between two nodes represents a connection on which the two news servers(More)
This paper proposes a new detection technique for fading-in/out text regions from MPEG1 bitstreams based on a Markov model. We focus on the properties that the luminance of a text region varies linearly in fading, and that text regions require larger amount of bits than non-text regions. These features are extracted directly from a target MPEG1 bitstream(More)
