Abstract
Data pre-processing forms an important element of pattern recognition proce dures for mechanical and structural damage detection. This paper discusses feature extraction and selection procedures. The discussion is focused on t ime-frequency and time-scale analysis. Case studies of damage detection exe rcises are presented for illustration.
