Automated Visual Inspection Based On Fermat Number Transform

摘要

This paper describes the application of Fermat Number Transform to the problem of automated visual inspection of 2-D Images. The transform is defiend in the field of integer numbers and as such all the computationsinvolved are exact thus eliminating errors due to rounding and/or truncation. The main features of the transform is that it is has a periodic structure and can be computed using just bit shift and add operations. This makes it well suited for use in pattern recognition prlblems. This technique has been implemented and tested successfully on a variation of image flaw types with promising results.
