Examples
- The key issue of improving the wavelet compression performance is how to efficiently organize the wavelet coefficients and to describe the information of image
如何有效地利用小波分解系数更好地表示图像信息是提高图像压缩性能的关键。 - 2 ) proposed a de - noise method based on wavelet packet coefficient shrinkage . the resolution of the method is finer than that of the method based on wavelet shrinkage in time domain and frequency domain
2 )基于donoho阈值去噪方法，给出了一种时频分辨率更高的小波包分解系数收缩的去噪方法。 - The kernel of improvement is that fractal predictive encoding is imported into mzte , and wavelet coefficient is encoded in zte mode or in fractal mode according to in which mode the encoding error is minimum
这种改进的核心思想是通过引入分形预测编码方法，根据具体情况，综合使用零树熵编码和分形预测编码方法对图像小波分解系数进行编码。 - The features are eventually calculated by the euclidean norms of the clusters . the combination of features extracted from wave structures , wavelet coefficients and frequency spectrum get better classification result than one kind of feature
本文还提取了舰船辐射噪声的波形特征，包络小波分解系数频率特征并与前述能量特征相结合，取得了比单个类型特征更好的分类效果。 - In order to import fractal into mzte , we need to expand the conception of wavelet tree . in this improvement method , the root of wavelet tree may be located in any frequency band , and it may not be a single coefficient , but a coefficient block
经过这样扩展概念的小波树，其根结点可以位于小波分解系数的任意频带上，且根结点不一定是单个系数，而可能是由若干系数组成的系数方块。
