The Limited Receptive Area (LIRA) neural classifier is proposed for texture recognition of mechanically treated metal surfaces. It may be applied in systems that have to
recognize position and orientation of complex work pieces during micromechanical device assembly as well as in surface quality inspection systems. The performance of
the proposed classifier was tested on a specially created image database with four texture types corresponding to metal surfaces after milling, polishing with sandpaper,
turning with lathe and polishing with file. The promising recognition rate of 99.8% was obtained.
