  • Image compression Based on Biorthogonal Wavelet transform
    IEEE International Symposium on Communications and Information Technology 2005. ISCIT 2005., 2005
    Co-Authors: Lin-pei Zhai, Wen-ming Li, Jiu-fei Zhou
    Abstract:

    A method for image compression of Biorthogonal Wavelet transform Based on lifting scheme with SPIHT (set partitioning in hierarchical trees) is proposed in this paper. Wavelet transform affords wide space for image coding algorithms because of its excellent space-frequency localization characterizations. The compact supported, symmetrical and Biorthogonal Wavelet has linear phase, so it is applied on image compression area widely. The lifting scheme is an efficient method for constructing the Wavelet filter after multiresolution. Under the condition of Biorthogonal, Biorthogonal Wavelet Base can be constructed freely according to the Wavelet performance. And it can quicken the implementation speed of the Wavelet transform. Analyzing the algorithm of lifting scheme is applying for constructing Biorthogonal Wavelet. Experimental results indicate that the method of the Biorthogonal Wavelet that has good performances with SPIHT is applying for image compression, so as image synthesis performs well.

  • The temperature signals of tank in hydraulic system de-noised by Wavelet transform
    Machinery Design and Manufacture, 2010
    Co-Authors: Shuai Xiao-yong
    Abstract:

    In order to carries on the condition monitor or the online automatic controls more precise,through the sensor to get the temperature data of the tank in hydraulic system and to carry on the denoising of the noised temperature signals.In view of the different Wavelet Base has the different de-noising effect,has discussed the orthogonal Wavelet Base and the linear phase Biorthogonal Wavelet Base to the different noise level signal,has obtained two Wavelet Base's general selection scheme,has selected the Biorthogonal Wavelet Base to the temperature signal de-noising processing.
