摘要：

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