In the 1960s a new special science of imagery began to develop – „imagery“, which deals with the study of the general image properties, the goals and tasks of their transformation, the processing and reproduction as well as the recognition of graphic images. Image forming, increasing image quality and the automated processing of aerial images including images captured from satellites, unmanned aircraft, radars equipped with synthesizing equipment and so on, are a subject of a number of researches and developments. The automatic analysis is widely applied in modern monitoring systems as the ones used in overwatch of areas, forests, asserting damage done on crops, reconnaissance and in the fire department services. In this article researches are conducted on the use of different image filtering methods from radar with synthesized aperture and aerial photography. The results indicate that filters can used for image pre-treatment under different scenarios, but the appropriate filter and its parameters need to be carefully selected.
