Journal of High Energy Physics 2011.07 (2011): 034 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA) ; We present a detailed study of a filtering method based upon Dirac quasi-zero-modes in the adjoint representation. The procedure induces no distortions on configurations which are solutions of the euclidean classical equations of motion. On the other hand, it is very effective in reducing the short-wavelength stochastic noise present in Monte-Carlo generated configurations. After testing the performance of the method in various situations, we apply it successfully to study the effect of Monte-Carlo dynamics on topological structures like instantons ; We acknowledge financial support from the MCINN grants FPA2009-08785 and FPA2009-09017, the Comunidad Autónoma de Madrid under the program HEPHACOS S2009/ESP-1473, and the European Union under Grant Agreement number PITN-GA-2009-238353 (ITN STRONGnet).
