Paper Abstract

In this paper, for the actual in-service pipeline detection, an edge detection method based on fourth-order B-spline wavelet multi-scale local modulus maxima is proposed. We extract defect edge using wavelet maximum algorithm, select fine length, invariant moment, gray scale energy and so on, several key characteristic parameters that are good for defect identification, and use BP neural network of single-output form for pattern recognition. By this method we complete the classification of the pipe weld joints and corrosion defects, and quantitative identification of corrosion defects.
