Weld location extraction in radiographic images using fuzzy rules generating method.

- Abstract
The present paper presents a method for weld location extraction in radiographic images. Images are processed line by line by applying fuzzy reasoning based on local pixel characteristics. For each pixel, values of spatial contrast and spatial variance are computed for evaluating the edge fuzzy membership value. The method proposed uses the machine learning approach for knowledge acquisition, which automatically generates fuzzy rules by learning from examples. Using this method, all welds are successfully extracted from 101 radiographic images taken from aluminium alloy welding parts.
