Quantitative Evaluation of Defect Based on Ultrasonic Guided Wave and CHMM

The axial length of pipe defects is not linear with the reflection coefficient, which is difficult to identify the axial length of the defect by the reflection coefficient method. Continuous Hidden Markov Model (CHMM) is proposed to accurately classify the axial length of defects, achieving the obje...
