Paper Abstract

In the IR thermography non-destructive testing, image blurring introduced by noises and heat diffusion in the sample is an important problem. In this paper, a serial of image processing methods are proposed to eliminate the influence caused by noises and heat diffusion. By use of these methods, image averaging, median-value, binarization and gradient alternation have been done. The processed images' characteristics are clear, and the error of detection is smaller than 5 percent. It is showed that the technique can effectively remove the blurring in images, improve image resolution and give us distinct images that meet the need of IR thermography non-destructive testing technology.
