Patent ID: 8374455

Claim:
A method for analyzing an image of hydrides in a metal alloy, the original image comprising pixels representing a sample of the alloy, wherein the hydrides are represented by groups of pixels, said method comprising steps of processing of the image in order to obtain the skeleton of the groups of pixels contained in the image, the skeletonization step being followed by an analysis step relating to the groups thus skeletonized, the analysis step executes a computation of the hydrogen content in the sample, an analysis step delivering a danger factor of a hydride, this danger factor being a value that is a function of the morphology of the hydride in its skeletonized representation, the danger factor of a hydride being a magnitude D defined according to the following relation: D = L 2 + θ 2 + 1 p 2 , where L represents the length of the hydride, θ its orientation and p its proximity to the other hydrides.
