Abstract: Abstract: - It is very common to use X-ray digital detection for the Small-bore steel tube butt weld. But the X-ray images have some shortcomings such as that contrast is not high, background noise is big, and the details can not be shown obviously, these shortcomings take a great inconvenience for the small-bore steel tube butt weld testing. So the detection efficiency can not be increased. Based on this, the Retinex algorithm is discussed and analyzed, such as single-scale of Retinex, multi-scale of Retinex, alterable framework of Retinex. Then it is applied to use an enhancement algorithm of improved Alterable framework on Retinex, and use this enhancement algorithm for X-ray image. This enhancement algorithm do not ask for much contrast of original image, which can effectively improve the original image contrast and image quality, the details of the image achieve the best visual effects. After the theoretical analysis and experimental results, we can see that, !
this enhancement algorithm can effectively enhance the image contrast, inhibit the background noise, compared with homomorphic filtering and histogram equalization algorithm. The standard of the image which is processed by this method can achieve the higher testing standard compared with homomorphic filtering and histogram equalization algorithm.
