Resumen: The topic of this paper is the description of procedures to remove the fringes from complicated astronomical data sets, where the interference pattern is not regular, combining topological and Gabor-based analysis. A first method is given and it involves two successive steps: first we perform an identification of the fringes using Gabor frames and latter we filter the connected components using computational topology methods. This is a new approach trying to get the benefit of filtering the harmonic representation by means of topological methods.
