Against the exiting question about which is hard to real-time analyze and measure speedy and exactly measurement of changing harmonic, this paper studies and realizes a harmonic analysis and measurement method based on reconstruction of wavelet packet decomposed coefficients. This paper puts forward a new concept of harmonic virtual value. Whats more, this paper studies, puts forwards and builds a detection method of harmonic virtual value and singularity. According to this method, power system harmonic track can be realized. This method provides theory basis for taking an effective method for harmonic real-time compensate. Using wavelet transform can make one voltage process decompose to a frequency band. According to sample frequency and decompose scale, frequency band can be confirmed. Harmonic content analysis is realized. All integral and non-integral harmonics are obtained. This method overcomes information missing resulting from spectrum leak, fence effect in traditional harmonic measurement. Reliability and accuracy of harmonic are improved. The self-adaptive power active filter is designed by combining the arithmetic of reconstruction of wavelet packet decomposed coefficients based on this theory.

The wavelet has a fractional factor, therefore the detector is more sensitive to the singularity of edges and can be effectively used to reduce faintness of edges in images. Numerical experiments indicate that the wavelet transform can be used in computer vision and real-time processing, such as edge detection, feature extraction, and texture analysis. To repress faintness of edges in images, an edge detector based on a B-spline smoothing formula of images is also proposed.
