摘要
小波基函数的选择和评估是将小波变换应用于技术科学领域的重要问题.其数学推导论证复杂且很难满足实际应用的需要.试图通过对图像压缩这一具体对象的剖析,以清晰、直观、物理的方法讨论实际应用中理想小波基的特性,利用计算机快速给出小波基优劣比较和正确选用的方法.
The ideal basic wavelets selection and evaluation would be very important for applications of wavelet transforms in the technology fields. The math proof is complicated but still difficult to meet individual practice problems. So try to discuss the characteristics of the ideal basic wavelets by some explicit and physical methods in image processing.Use computer can submit some methods so as to select wavelets and discuss their criteria quickly.
