Best bound rule
最佳界法則 -
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
這種方法依據r - d準則優選出最佳小波包基,在優選過程中,用到了最佳量化法和霍夫曼編碼,從而保證了在給定的失真內使得壓縮比做的最高,取得了比較滿意的效果,為將來在dsp上實時的實現做好了鋪墊。
