Abstract
Features &e extrzted from the angular specrwn of light scattered fnxn the sur(e of machined surfxes which are then used as inputs to a hrarcha1 neural net. The net is "U1nCd by aselected training set of feures from surfaces whose quality has already been independently establishet These samplessicrepeatedlypresented to the sensors and the network makes a deCISIOn about the surface roughness which is then compared to the rrect answa, and the TOf used to modify the conntion weights. Following this training pcziod, the net is be able to identify the quality of new surfes presented to IL Indeed, it is able to ck, so even in the presence of noise which is likely to be caused by poor illumination. Results, using this laser scattering technique, from a set of prepared sirfaces are dixussed with regard to fusion of different features in der to obtain an adequate measure of surfe roughness ung the harchkal newal nwor
