Motion estimation (ME) plays an important role in video compression. Block-based ME has been adopted in most video compression standards due to its efficiency. In this paper, we p...
This paper describes a novel suggestive interface embedded in a smart camera prototype aimed at aiding home movie makers. We focus on the problem of generating shot capture sugges...
In conventional video coding, the complexity of an encoder is generally much higher than that of a decoder because of operations such as motion estimation consume significant com...
The detection of LSB steganography is a question of common interest in the research of steganalysis techniques. In this paper, the distribution of the difference between the curre...
The informal information can be so intuitive, emotional, personal, honest and subjective that it is very difficult to get them from the formal media. In this paper, we demonstrate...
Video transmission over unreliable packet network is in general hampered by the packet losses and constraint by stringent playback deadline. With these two key factors in consider...
The increasing popularity of distributed and collaborative applications prompts the need for secure communication in collaborative groups. Some distributed collaborative key manag...

Person-based indices and timelines can enable fast and non-linear access to recorded meetings. This paper focuses on how to automatically construct those indices and timelines by ...
Shooting videos with a hand-held camera introduces shaking, which incontrovertibly reduces video quality. Digital video stabilization is a process to compensate for camera motion ...
Most of the current speech transmission systems are only able to deliver speech signals in a narrow frequency band. This narrowband speech is characterized by a thin and muffled ...
