Taking the negative pressure wave produced by pipeline leakage as a transient signal, the multi scale wavelet transform can be utilized to identify the pipeline leakage signal in local.
利用多尺度小波变换，把管道泄漏产生的负压波信号作为瞬态信号，来识别管道的局部泄漏特征。
Finally, the fusion image is obtained by taking the inverse IHS transform. The experiments prove the performance of new scheme is better than those of IHS fusion method and typical WT fusion method.
实验结果证明融合算法较IHS变换算法和常用的小波融合算法有更好的融合效果。
