小波包基 meaning in Chinese
wavelet packet basis
Examples
- Signal denoising algorithm and its application based on best wavelet packet basis
基于最优小波包基的信号去噪算法及其应用 - A method for denoising and suppressing clutter based on best tree wavelet packet analysis is developed
提出基于最优小波包基的非线性滤波法进行杂波抑制。 - When combined these methods together , we can get a better result , e . g . integration of wavelet packet analysis with image processing , can make the wavelet packet analysis even more robust
多种处理方法集成，如基于最优小波包基方法和图象分析方法相结合等，对于信号提取将获得更好的结果。 - The method directly executes wavelet packet decomposition of handwriting texture using wavelet packet basis db6 at scaling 3 in 2d space , then reconstructs the decomposition coefficient of 15 wavelet packet best basis which are took by shannon entropy cost function
该方法直接在二维空间上由db6小波包基对笔迹纹理实施3尺度小波包分解，再在由以香农熵为代价函数提取得到的15个小波包最好基处对分解系数实行重构。 - We put forward an adapted wavelet packet transform method - - adapted wavelet packet transform based on r - d rule which selects the best wavelet packet base according to r - d rule , in which best quantization method and huffman coding are used . this method produces the best compression version such that the error upon reconstruction is within an upper bound fixed a given value and obtains satisfactory compression results
这种方法依据r - d准则优选出最佳小波包基，在优选过程中，用到了最佳量化法和霍夫曼编码，从而保证了在给定的失真内使得压缩比做的最高，取得了比较满意的效果，为将来在dsp上实时的实现做好了铺垫。
