Underwater communication networks are currently being developed for use in underwater control systems, underwater telemetry systems, and underwater image transmission systems. The transmission bandwidth and transmission rates of an underwater communication system are low, and its transmission delay is high. In this paper, we propose a direct mapping orthogonal variable spreading factor (OVSF)-b...

Early warning systems are key components of strategies to reduce risk. This research, by adopting a systematic approach in the management of the risk of desertification and by including previously developed models and systems, offers an integrated efficient structure in terms of early warning for the risk of desertification as a pilot system for semi-arid areas of west Golestan Province in IRAN...

In this paper we discuss general requirements for parallel implementations of image processing algorithms. Of special importance are the communication demands in the parallel system which are determined by the algorithm under consideration. These communication demands are decisive for determining the best way to distribute the image data to the network processors. Analysing these factors for so...

We propose a new interpretation platform dedicated to video communication. Basically, a video communication system takes an image flow from a camera and broadcasts it in a computer network. The goal of interpretation is to enable the video communication system to adapt automatically the broadcasted image flow, using image filtering, blurring and zooming. For that we need to detect and track ind...

Installing a live camera in an office or laboratory can provide reliable high-quality communication among collaborators who are physically separated, but may also lead to privacy concerns. We propose a technique for displaying presence information using a three-dimensional object as a mask that covers the image of people in the live camera system. Our technique enables information to be shared ...
