Compressive Underwater Video Camera
A tertiary goal, which we plan to explore in depth in future research, is the integration of image compression with automated target recognition (ATR). Two cases are of interest to this study. First, we have shown that one can achieve increased processing efficiency by applying specially configured ATR operations to compressed imagery [Sch97c,d]. Second, we have developed techniques for prefilt...
متن کاملA High Speed Underwater Acoustic Modem for Video Communication
A novel high speed OFDM based underwater modem with phase coherent modulation has been proposed for video communications. The key to achieve this objective is passband sampling, which enables us to perform coherent detection with precise control over the carrier phase by using digital carriers. Currently commercially available long-range underwater mo-dems provide a maximum data rate of 38 kbps...
متن کاملImplementation of an acoustic localization algorithm for video camera steering
Advances in wireless networking and sensor network design open new prospective in performing demanding collaborative sensing and signal processing. This project was motivated by the ambitious plan of designing and implementing acoustic applications in low-cost distributed wireless sensor networks. As first step, we considered the problem of acoustic localization through a set of distributed sen...
متن کاملAdaptive Underwater Acoustic Communications
Underwater wireless networks consist of mobile and static nodes, which usually communicate using the acoustic channel since radio transmissions attenuate rapidly and optical communication is only suitable for short distances. The underwater acoustic channel is plagued with issues of high transmission power requirements, rapidly changing channel characteristics, multi-path echoes, possible high ...
