Abstract:
1. A method for controlling quality of a manufacturing process for recognizing defects in result of a production, the method comprising: acquiring, by detecting one or more quantity of the production of said manufacturing process, one or more real signals produced by a machine involved in the manufacturing process, where the one or more real signals are indicative of the quality of said manufacturing process; providing one or more reference signals corresponding to said one or more real signals and indicative of a good-quality process for the manufacturing process; obtaining a transformed signal from said reference signal; obtaining a transformed signal from said real signal; converting each of the transformed real signal and the transformed reference signal into a respective vector of energies, where the vector of energies comprises an integer number k of frequency values; and comparing said one or more reference signals with said one or more real signals in order to identify the defects in the result of the production, wherein said comparing comprises:
