| Abstract: | The digital image processing method for automatic magnetic particle testing system was discussed. The constant false alarm rate (CFAR) technique and conditional tracking technique were applied to obtain high quality binary image. The dendriform searching method and identification algorithm based on the property of flaw were used to satisfy automatic magnetic particle testing. |
