Aiming at the peak extraction problem in the radon space, a peak extraction method based on AR model is proposed to detect component crack value.A profile analysis technique is used to take profile in Radon space and reconstruct profile with AR model to get a sharp and prominent peak for crack value extraction.Intensive experiments have shown that the proposed method is effective in estimating the component crack and lessening peak extraction difficulty.
