Abstract

This work deals with the challenge of surface extraction using a combination of Teager-Kaiser operators and B-splines in the context of coherence scanning (or white light scanning i.e, WLSI) interferometry. Our approach defines a B-spline regularization model along surface profiles extracting their features by means of parameters locally describing fringe signals along the optical axis, while most studies are limited to a one-dimensional signal extraction. In doing so, we take into account four characteristic parameters under Gaussian hypothesis. The interest of the proposed strategy consists in processing the layers present in a material, in a context of soft roughness surfaces. The efficiency of our unsupervised method is illustrated on synthetic as well on real data.
