| Abstract: | This paper is concerned with a new method of compression using the second generation wavelets based on the lifting algorithm, which is a simple but powerful wavelet construction method. The compression ratio of this method is about twice as much as the common compression software.Its successful application in a real time monitoring & test system of hydraulic power generating sets has been proved that it is a promising compression method. |
