根据地震同相轴及断层的特性 ,本文基于 Bubble函数构造母小波函数 ,并采用高斯函数为父函数 ,对地震资料进行了二维小波分析 ,提取了地震同相轴的边缘信息 ,并二值化为二值图像 ,然后用 CB形态滤波删除图像中延展度小的连通分量 (噪声 )。理论和实例计算表明 ,该方法具有很好的效果。
According to the characteristics of seismic events and faults, this paper constructs the mother wavelet function based on the Bubble function, and uses the Gaussian function as the parent function to perform two-dimensional wavelet analysis on the seismic data. The edge information of the seismic events is extracted and binarized to Binary image, and then use the CB morphology filter to delete the image with less ductile connected components (noise). Theoretical and practical calculations show that this method has a good effect.
