A computer 21 which is the core of image processing calculates an edginess which is an image variation from a differential value of data for adjacent picture elements in a step SA110, and determines object picture elements by selecting only images with a large variation in steps SA120, SA130. The step of scanning the barcodes produces, on the touch-sensitive screen of the hand-held computer, product information concerning the product contained within the scanned bottle including a silhouette of the bottle. The invention also relates to a method for producing dental shaped parts with a blank body made of tooth restoration material, from which the entire shaped part can be machined in a machining device by a tool for removing material. The propellant 9 is arranged in an end-burn configuration and housed within the combustion chamber and the propellant support 11,12 is located between the propellant 9 and the plenum chamber 8 and is capable of preventing entry of unburnt propellant into the plenum chamber 8 while permitting, in use, the substantially unhindered transfer of propellant combustion products to the plenum chamber 8.
