Abstract: One of the chief works for inspecting spot weld quality by X-ray to obtain an ideal and uniform digital image. This paper introduces three methods of image background simulation algorithm, and the effect of background correction was, compared. It may be safely said that Kalman filter method is simple and fast for general image, the FFT method has a good adaptability for background simulation.
