Abstract: Ecuador is a country with a great number of volcanoes, 27 active in the part continental and insular, of which three are in full process eruptive by which the government Ecuadorian estimated necessary the monitoring constant of them volcanoes of the territory, however, all the process is manual both the analysis of images as the of data. By that arises the need of creating a system embedded that allow control an or several functions with resources limited and in conditions environmental hostile doing the processing and analysis of images through software free of way autonomous. By this reason is created an algorithm that will allow detect the presence of flows as well as the trajectory of them themselves for which is necessary mitigate in the possible the noise inherent to the processing digital of images in order to generate alerts in case of exist a phenomenon volcanic.
