1. Introduction
- This research aims at processing an overlapped sound for acoustic event detection (AED) system by means of the source separation technique. The proposed system can be applied in various applications. (e.g. Home/Office surveillance system, Personal life-logging)
2. Relevant algorithms
NMF non-negative Matrix Factorization (NMF)
NMF algorithm decomposes a matrix V into two nonnegative matrices
In the acoustic separation problem using NMF, a nonnegative matrix V can be regarded as a magnitude spectrogram
Basis W and time evolution H are generated by decomposing V
Update algorithm of the NMF
