中文拼音 [zhòusuōxìshǔ]
驟縮系數
英文
coefficient of sudden contraction-
The sensitivity of one - dimension consolidation degree to the uncertainty of seepage coefficient, void ratio and compression coefficient is analyzed, then, the reliability of percent consolidation is analyzed with jc method and the steps of calculation are presented
分析了固結度對滲透系數、孔隙比和壓縮系數三個參數不確定性的敏感性。利用jc法分析了一維固結度的可靠性,通過實例驗證用所給的迭代步驟,計算結果收斂很快。My principal work is these : transforming image in wavelet at first, then encoding wavelet coefficients in sofm arithmetic methodology, lbg arithmetic methodology, dpcm encoding step by step, wavelet zero tree compression separately, reconstructing the image at last, so researching how to improve compression ratio, hi addition, the article puts forward a new arithmetic methodology, sl arithmetic methodology, on the base of comparing sofm arithmetic methodology with lbg arithmetic methodology what it needs emphasis is the variety of reconstructed image because of the diversity of mother wavelet
本人所做的工作主要圍繞著這樣的步驟:將圖像數據先進行小波變換,然後分別應用sofm演算法、 lbg演算法、 dpcm分步編碼、小波零樹壓縮等對圖像小波系數進行編碼,最後重構圖像。 akqnk44 wa從而研究如何能夠提高圖像壓縮比,並比較了各演算法在圖像壓縮中的特點。另外,根據sofm演算法、 lbg演算法在圖像壓縮中的各自特點,提出了一種新的算祛一七l演算法。The algorithm is based on the optimum quantization step for each dwt coefficient according to psychovisual considerations which derived from methods in image compression
本文的演算法基於圖像壓縮演算法中利用心理視覺給出的dwt系數的最優量化步驟。
