This paper mainly deals with the relationship between window function and impedance tapered line function. The latter is the extension of the former from the discreet domain to the continuous domain. Take the transformation of window functions as the tapered line functions, a detailed derivation of the character impedance and reflection coefficient is(More)
Wavelet space entropy is the extension of wavelet time entropy in the two-dimensional space, which can make use of the wavelet to detect sudden change in the signal. It's a good method to eliminate the effect of noise, but at the same time, the edge it detects is coarse and not integrated. Canny operator is a classical edge detection operator that has a(More)
