In this paper, a method for the detection and classification of defects in weld radiographs is
presented. The method has been applied for detecting and discriminating discontinuities in …

An effective and adaptive method is proposed to automatically detect weld defects using
defect tracking in real-time radiographic image sequence of a moving weld. Firstly, a defect …

Quality inspection and defect detection play a critical role in infrastructure safety and integrity
specially when it comes to aging infrastructure mostly owned by governments around the …

Automatic weld defect detection based on real-time X-ray image plays a vital role in
improving the automation level of radiographic inspection in industry. Most of the existing …

ABSTRACT A three-step procedure is described which utilises wavelet de-noising, shape
from shading (SFS) method and the Harris corner detector (HCD) for improved defect …

Detection of hidden corrosion within aircraft structures poses a significant challenge in non-
destructive testing (NDT) methodologies, particularly in the electromagnetic testing (ET) …

Terahertz (THz) spectroscopy is an important method in noninvasive detection and
diagnosis for historic relics. A new nondestructive testing (NDT) method based on terahertz …

Inspection of welded joints plays a crucial role in finding internal flaws and defects in
specimens, finding quality of welded joint in early stage will reduce damage and provides …

Monitoring and quantifying crack initiation and growth are of primary importance both for
material performance evaluation and design and for structural damage assessment. While …

This paper presents a fast and adaptive method for weld extraction. Firstly, a fast algorithm
was developed to recognise and alarm welds with large surface defects such as burn …
