In addition, it serves as an alternative to focus through an Open Source tool with a low computational cost. As a preliminary result, pseudo-images of two regions of Venezuela were processed with the developed algorithm and a qualitative comparison with pseudo-images of level 1 of the same regions provided by the European Space Agency is discussed.</p>}, number={4}, journal={IEEE Latin America Transactions}, author={Franchi, Indira and Zozaya, Alfonso}, year={2021}, month={Jun.}, pages={567–574} }
