Bayesian Networks-Based Defects

ClassesDiscrimination in Weld Radiographic Images

Aicha Baya Goumeidane, Abdessalem Bouzaieni, Nafaa Nacereddine, Antoine Tabbone

Abstract: Bayesian (also called Belief) Networks (BN) is a powerfulknowledge representation and reasoning mechanism. Based on probabilitytheory involving a graphical structure and random variables, BN iswidely used for classification tasks and in this paper, BN is used as aclass discrimination tool for a set of weld defects radiographic imagesusing suitable attributes based on invariant geometric descriptors. Testsare performed on a database of few hundred elements where the resultsare outstanding and very promising, since they outperform those givenby powerful SVM classifiers.

Keywords : Bayesian networks, weld defects, Geometric descriptors, radiography

The experimental results show that the SVM classifier is an efficient automatic weld defect classification algorithm and can achieve high accuracy percent and is faster than

Weld defect features are computed from the segmentation result (final binary level set).. We have computed several features; they are ranked in two categories: Geometric features

Weld defect segmentation and restoration from rough radiographic image: (a) Defined ROI in rough weld radiographic image, (b) ROI image with initial contour (dashed green line)

The particularity of this model is the capacity to detect boundaries’ objects without need to use gradient of the image, this propriety gives its several advantages: it

Fractal image compression, based on concepts of iterated function systems (IFS), consists of partitioning blocks and approximates each block by a transformed codebook block derived

Abstract : This paper presents a variational level set approach applied to segment images; especially to detect welds defects in radiographic images.. Level set methods are a

Also the level set function is easily initialized with a binary function, which is more efficient to construct than the widely used signed distance function (SDF). The
