Implementation and discussion of the Pith Estimation on Rough Log End Images using Local Fourier Spectrum Analysis method

In this article, we analyze and propose a Python implementation of the method "Pith Estimation on Rough Log End images using Local Fourier Spectrum Analysis", by Rudolf Schraml and Andreas Uhl. The algorithm is tested over two datasets.
