Open the CIPO recordAbstract From the Canadian patent
The automatic defect detection process on a fluoroscope image of a complex part consists in segmenting the fluoroscope image into two classes of area so as to obtain a binary image called a mask, in which the zones that can be assessed and those that cannot are given the values 1 and 0 respectively, then applying to the fluoroscope image conditional morphological transformations developed from a conditional structuring element. The conditional structuring element is obtained by intersection between a traditional structuring element and the mask. Application in particular to the assessment of cast vanes by fluoroscopy.

Why it's free to use
- Filed August 4, 1997. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 4, 2017.
