log-log transformation
1.Since scaling exponents fitted from many fast Fourier transformation (FFT) power spectra of the log intensity of laser beam in the turbulent atmosphere go beyond the theoretical bound, the discrete wavelet transformation (DWT) power spectrum was introduced.
2.After geometric transformation of image space, resampling of image pixels, and transfer from DDB to DIB bitmap mode, the original images acquired in television log become some bitmap files which can more properly be used in the geological explanation.
