The invention relates to a system and a defect detection method on an object to calculate differential between various subdivisions for detecting an abnormal indicative subdivision of failure beginnings.
The invention relates to a system and a defect detection method on an object (11), comprising the steps of: -Train an image (13) representative of said object (11) from signals (9) relative to the object , -construct subdivisions (15) of said image according to the self-adaptive resolutions and -Calculate differential between various subdivisions for detecting an abnormal indicative subdivision of failure beginnings.
