HAN Xiao-Jun, SHI Ze-Jin, LI Ya-Lin.An Improved Algorithm for Pick-up of Seismic Waves by Fractal Dimension. Petroleum Geophysical Prospecting, 2002, 37 (1): 6 0 ~ 6 3 This paper presents an improved first arrival Wave method. The method uses the basic principles of segmentation to calculate the fractal dimension along the seismic trace and picks up the first arrival from its changing traits. However, the former method is time-consuming in calculation, and the result depends on the accuracy of interpolation. The calculation method proposed in this paper avoids the interpolation problem in the calculation process, which improves the calculation speed and enhances the stability of the calculation results
