摘 要: 边缘检测和相干体技术都能在一定程度上描述河道的边界特征,通过在常规相干体技术流程中引入图像处理中的边缘保持平滑滤波算法,将2种方法相结合,能够有效地压制噪声,更好地保持数据的边缘特征。实际资料处理表明:基于边缘保持平滑滤波的相干体技术能够有效地突出地质体的边缘特征,增强地质体内部的共有特征,在河道砂体的边界刻画中取得了较好的效果。
关 键 词: 固体地球物理学;边缘保持平滑滤波;相干体;河道砂体

Abstract: The edge detection and coherency cube technique are valid to depict the boundary of channel sand at some degree. The edge-preserving smoothing filter algorithm from image processing has been adopted into the common coherency cube technique flow. With the combining of these two techniques, the noise has been pressed and the boundary characterization has been preserved. The actual data processing showed that the coherency cube technique based on the edge-preserving smoothing filter is useful in the boundary description of channel sand. The boundary characteristic of geology body is highlighted and the internal common characteristic is strengthened.
Key words: solid geophysics; edge-preserving smoothing filter; coherency cube; channel sand
