Fig. 8.13 Comparison of different localization methods for S1 and S2
Fig. 8.14 Comparison of different localization methods for S1 and S3
DTCWT-Correlation perform well to locate the leak source in short distance (14.5 m)
but they became problematic when the measuring range increases to 24 m (Fig. 8.14).
According to their results, a susceptible leak occurs at 3 m, 12 m and 9.5 m, respectively which are deviated from actual leak location. As of propagating distance
