改进后的模糊边缘检测方法在裂缝检测中保留了更多的图像灰度信息,因此,检测结果既保留了更多的局部裂缝分布特征,又能明显地预测裂缝发育带的整体分布特征,并且计算速度比改进前有明显提高。该方法在实际资料处理中取得了令人满意的效果。

An improved fuzzy edge detection method is presented for detection of fractures. The detected results not only provide the local details of fractures, but also can depict the distribution of fracture zone clearly for the method can retain the grey scale information of a seismic image. In addition, the computation efficiency was also improved.
