Leak Detection in MDPE Gas Pipeline using Dual-Tree Complex Wavelet Transform

The pipeline system plays the important role in the industry and commonly use as media transport in the piping field on the land or on the sea as well. They are buried underground or situated in the wall of the buildings. The maintenance should be done properly to avoid any leakage to the surroundin...
