Defect Extraction of ICT Images Based on Adaptive Morphological Filtering

  • Received Date: 17 Jun 2008
  • Publish Date: 18 Feb 2009
  • To overcome the shortcomings of the current defect extraction methods for ICT(industrial computerized tomography) images,an adaptive filtering method based on the mathematical morphology was proposed.Firstly,with this method,the primary region of a structural element is automatically chosen in the light of region size after the watershed transformation of full ICT images.Secondly,the ellipse fitting operation is applied to the boundary of the primary region to get the final structural element.Then the background images are gotten by the closing operation of the mathematical morphology on the original images using the final structural element.Finally,the defect images are obtained by subtracting the original image from the background images.The experimental results show that compared with the current methods,the proposed method can obtain a good result of defect extraction of ICT images.
