| Abstract: | Independent component analysis (ICA) method was used to decrease the electromagnetic noises in the inspection of seabed pipelines by magnetic flux leakage method. The principle of magnetic flux leakage testing and negentropy law of ICA were introduced. Experimental data were processed using relative analysis tools and results showed that ICA was used to separate defect signals from electromagnetic noises effectively in laboratory. |
