The objective of this work is to identify geological circular forms, impact and volcano craters, using satellite images. The recognition of objects (circular forms) in the scene is the last step in a processing chain, which can be described in four phases: image preprocessing, pattern detection, pattern recognition, and identification of the targets (models). The paper presents the detection of circular forms on images including the south region of the Minas Gerais State in Brazil.
