Abstract
Method implemented by computer means for optimizing a measured contour of an opening of a spectacle frame, the method comprising: a contour data providing step, a working contour defining step, during which a working contour of the spectacle frame is defined, a first contour cost function providing step, during which a first contour cost function function of the mth derivative of the curve of the contour is provided, a set of contour cost functions providing step, during which a set of contour cost functions is provided, a global contour cost function evaluation step during which a global contour cost function is evaluated, a contour modifying step, during which the working contour is modified, wherein the global contour cost function evaluation and contour modifying steps are repeated so as to minimize the global contour cost function.
