摘要
给出一种寻找信号和图像的最佳小波分解方法 .对正交小波、对称正交小波、双正交和对称双正交小波 4种情形进行了讨论 .结果表明 。
The present paper presents a method of looking for the best wavelet transform which makes the low pass signal have the best approxiamtion to the original signal. We have solved the title problem for four cases, orthogonal, symmetric orthogonal, biorthogonal, symmetric biorthogonal wavelet filters, and improved the compressive image quality and increase compressive ratio.
