摘要
The basic principle of decomposition and construction of Steerable Pyramid used to detect faults was given a detailed introduction. The characteristics and distribution of faults in different scales and directions after the decomposition of Steerable Pyramid were studied and faults information obtained through a re-construction. The information was not only concerned with the edge detection of fault, but also enhanced the fault itself. The images of channels were obtained after the faults were wiped off. It is proved that using Steerable Pyramid to detect faults and channels is a successful method. But the effect is susceptible to smoothing parameters, which should be selected based on the characteristics of the inputting figure.
