X-ray Digital Image of Weld Defect Based on Wavelet Transform Edge Detection
In the digital-ray detection, in order to better detect weld image defect edge,method based on wavelet transform processing was proposed. According to the characteristic of X-ray digital image, based on MATLAB R2012a,a complete set of welding defect edge detection process was designed which can be applied to randomly selected digital images ray detector, which has strong de-noising effect, along with good continuity. The feasibility of the algorithm was confirmed through tests, and better test results were gotten compared with other edge detection operators.
