  • An efficient smoke detection algorithm on color video sequences obtained from a stationary camera is proposed. Our algorithm considers dynamic and static features of smoke and composed of basic steps: preprocessing; slowly moving areas and pixels segmentation in a current input frame based on adaptive background subtraction; merge slowly moving areas with pixels into blobs; classification of the blobs obtained before.

  • Since the digital representation of raw video signals requires a high capacity, low complexity video coding algorithms must be defined to efficiently compress video sequences for storage and transmission purposes. The proper selection of a video coding algorithm in multimedia applications is an important factor that normally depends on the bandwidth availability and the minimum quality required.

  • The near future will witness the universal deployment of the third-generation mobile access networks that are expected to revolutionise the world of telecommunications. In addition to conventional voice communication services provided by the second-generation GSM networks, the third-generation mobile networks will support a greatly enhanced range of services due to the higher throughput made available by embracing a number of new access technologies. These include TDMA and a variety of CDMA radio access families such as the direct sequence Wideband-CDMA (WCDMA) and multi-carrier CDMA....

  • 3D models are getting more and more attention from the research community. The application potential of 3D models is enormous, especially in creating virtual environments. In Vietnam National University - Hanoi, there is a need for a test-bed 3D environment for research in virtual reality and advance learning techniques. This need raises a very good motivation for the research of 3D reconstruction. In this paper, we present our work toward the creating of a 3D model of Vietnam National University - Hanoi automatically from image sequences.

  • Video sources produce data at very high bit rates. In many applications, the available bandwidth is usually very limited. For example, the bit rate produced by a 30 frame/s color common intermediate format (CIF) (352288) video source is 73 Mbits/s. In order to transmit such a sequence over a 64 Kbits/s channel (e.g., ISDNline), we need to compress the video sequence by a factor of 1140. A simple approach is to subsample the sequence in time and space. For example, if we subsample both chroma components by 2 in each dimension, i.e.

  • Assumptions. We assume that the logs faithfully capture events and their causality in the system’s execution. For instance, if the log declares that event X happened before event Y, we assume that is indeed the case, as the system executes. We assume that the logs record each event’s timestamp with integrity, and as close in time (as possi- ble) to when the event actually occurred in the sequence of the system’s execution.

  • In multiuser rate allocation problem, a set of transmitters want to transmit the video sequences to corresponding receivers through a common channel that is shared by all transmitters. Since the transmitters compete for the same resource, i.e., channel bandwidth, they form a non-cooperative social network. The key problem in this social network is how to e±ciently and fairly allocate data rate among di®erent users.

  • In this work, we propose a novel ROI-based bit allocation (BA) method which can adaptively extract and increase the visual quality of ROI while saving a huge number of encoding bitrates for video data. In the proposed method, we first detect and extract ROI based on the depth information obtained from 3D-TV video coding sequences.
