ABSTRACT:
A process for automatic detection of the assessable areas within an image of a mechanical component comprises a first phase during which different areas of at least one reference image are detected by means of manual segmentation, a second phase during which marking parameters for the areas of the reference images are defined and fixed, these marking parameters being simplifying transformations and thresholding intervals for the reference images making it possible to obtain optimal quality of separation of the areas, and a fully automatic third phase during which the area-marking parameters defined and fixed during the first two phases are used to mark the assessable areas of new images, and the exact outline of said areas is determined using the watershed line method.
