A computer-implemented method for measuring the three-dimensional geometry of a mineral glass-based glazing during or just after a temperature shaping operation. The method implements digital processing and calculations, based on the principles of stereocorrelation, of digital images of a random light pattern projected onto the surface of a transparent glazing. It makes it possible in particular to determine the shape or the three-dimensional geometry of a transparent glazing, the surface of which not be totally opacified and/or which radiates under the effect of temperature.

A method for selecting a filtering structure for a gas laden with particulates, said structure comprising a filtering part formed from a porous ceramic material and comprising at least one, and preferably a plurality, of porous walls, said method being characterized in that, starting from a first image of the surface of the wall, a processing operation is carried out on said first image comprising a morphological erosion by a structuring element in such a manner as to obtain a second characteristic image of the regularity and of the uniformity of the microstructure of said wall. Silicon carbide filtering structure obtained by application of said method.
