APPLICATION OF ROCK SOLID ATTRIBUTES FOR ROBUST IDENTIFICATION OF GLASS BREAKS ACOUSTIC SIGNALS VIA WAVELET TRANSFORMATION

Ireneusz Bemke, Romuald Zielonko
Abstract:
Nowadays, the most popular method of glass breaks detection in alarm systems, is analysis of acoustic signals (because of performances and costs). Often used method are based on detection of some characteristic frequencies, is insufficiently resistant to other (false) signals. As papers [5] and [6] show, signal decomposition by JTFA is more useful for this kind of signals. To develop a robust method of glass breaks detection the authors applied Wavelet Transformation. Presented in [1] and [2] early results did not meet strong requirements of VdS standard presented in [6]. In this paper a new approach based on Wavelet Transformation and Rock Solid Attributes (used in geology) is presented.
