Effectiveness of flaws detection process using various algorithms of background generation and various algorithms of image thresholding was evaluated. The results of background generation using a median filter method, a polynomial approximation method and an iterative Gaussian approximation method were presented. The received background images were subtracted from the base image. After background subtraction process the global and local thresholding algorithms were applied. All analysis were carried out using digital radiographs of real welds.
