Application of mathematical morphology to the analysis of X-ray NDE images

Ever since the beginning, man has been in the relentless pursuit of perfection. From stone age to space age, from caves to condominiums, from carts to planes, trains and automobiles, his drive for consummation has grown considerably. The high quality products that are available in the market at the turn of the twenty first century are living legacies of his unyielding endeavor for excellence. But one fact that most people do not realize is the amount of time and money devoted to quality control and non- destructive evaluation (NDE) that is responsible for the high quality of products. In the past, people used to tap earthenware and other materials as a means of non destructive testing for defects in the material. They could sense the defects by the nature of the sound propagated through the material. The ultrasonic method of NDE is an extension of this principle
