Abstract
This paper presents a fast segmentation method using fuzzy sets theory applied to astronomical images interpretation. It consists in separation in two classes («stars and other objects») with human-like decision. This separation constitutes the first step in astronomical images analysis, before spectrographic analysis and high level interpretation. A fuzzy segmentation isolates regions relative to objects and evaluates shape parameters for each region. Then, combined criteria are computed on the obtained fuzzy regions. The decision is founded on rules using these combined criteria. For each object we obtain the location, the orientation and the membership degrees to each class, then we build two images coding the membership degrees for each pixel to each class. With this method the use of fuzzy concepts in the first step allows to use fuzzy reasoning all along the classification process.
