Fuzzy seismic facies detection with interactive defuzzification method

This work addresses the problem of seismic facies detection in order to understand the subsoil organization. A fuzzy fusion system is used to achieve this task. In this paper, an interactive defuzzification, based on /spl alpha/-cut analysis. is proposed. This method allows to involve interpreters in the final decision. Associated with this interactivity between interpreters and the detection process, a performance measure is defined to assess the result quality.
