Because the Local wave T-F spectrum can be showed in the gray image, so we use the moment invariants of time-frequency image as the fault features.
由于局域波时频谱可以表示为灰度图像。因此，利用图像信息的不变矩进行故障特征提取。
Fault zone F(14) near the Liaohe River would be a significant target for gold dePOSits.
潦河附近的F（14）断裂带是一条规模较大的含金破碎带。
Fault zone F(14) near the Liaohe River would be a significant target for gold dePOSits.
