The Application of MATLAB in Welding Image Processing

Abstract:

Firstly the margin-detection methods commonly used are presented in this paper. The algorithm idea is that the edge points correspond to the local maximal points of original image’s gray-level gradient. These algorithms are very sensitive to noises if these images mixed much noise, which usually leads to wrongly detect noise points as marginal points, and the real edge can not be detected as the interference action of noise. However, we perform kinds of pretreatments on these images under the MATLAB environment and adequately make use of the functions of image processing toolbox to satisfy the need of edge detection. Lastly, Combined with practical examples, the specific application of MATLAB in edge detection is analyzed in detail.
