Pre-processing and post-processing algorithms improve on the performance of a video compression system especially by removing spurious noise and insignificant features from the original video data. So that this will increases compression efficiency, attenuates coding artifacts and mainly improving the quality of Video data. And more over existing video compression standards like MPEG, H.26x series...
The use of two non-linear black-box approaches, phase-space reconstruction (PSR) and artificial neural networks (ANN), for forecasting river flow dynamics is studied and a comparison of their performances is made. This is done by attempting 1-day and 7-day ahead forecasts of the daily river flow from the Nakhon Sawan station at the Chao Phraya River basin in Thailand. The results indicate a reasonably...
The application of the concept of chaos theory in hydrology has been gaining considerable interest in recent times. However, studies reporting the existence of chaos in hydrological processes are often criticized due to the fundamental assumptions with which the chaos identification methods have been developed, i.e. infinite and noise-free time series, and the inherent limitations of the hydrological...
