Paper Abstract

The suggested method provides a fast noise and background reduction simultaneously as a preprocessing step of interferograms extrema tracing. The method consists with Hartley transformation, filtration, differentiation, inverse Hartley transformation and binary pattern formation. The discussing advantages are in computing aspect.
