The basic conception of dyadic wavelet transform is introduced The practical expression of dyadic discrete wavelet transform of digital signal is presented.

An investigation and analysis on the issue of the relationship between Xian tian tu and binary system;

Had Leibniz not seen the Xian tian tu before he founded the binary system? —— A textual research of European literature about culture exchange between China and the West in the seventeenth century;

Computers need numerical value change between binary system,octal system and decimal system The fortran77 is used in the programming to perform the numerical value converting.

The four-level center B-spline semi-orthogonal dyadic wavelet was used to identify the singular points of the faulty current,and the theoretical support is analyzed.

The property and algorithm of dyadic wavelet function and dyadic wavelet transform basing on B spline are introduced.

This paper present the existing image edge detection method based on dyadic wavelet transform first,and then analyzed the drawback of the method.
