SegmenterMIREX2014

Segmentation algorithms for MIREX 2014.

It contains the following algorithms for boundary identification:

• Convex Non-negative Matrix Factorization (C-NMF)
• Foote
• Structural Features (SF)

And the following segment labeling algorithms:

• C-NMF
• 2D-Fourier Magnitude Coefficients (2D-FMC)

Version 1

C-NMF for both boundaries and labels. To run:

./segmenter.py input.wav -o output.lab

Version 2

Foote for boundaries and 2D-FMC for labels. To run:

./segmenter.py input.wav -o output.lab -s 2dfmc -b foote

Version 3

SF for boundaries and 2D-FMC for labels. To run:

./segmenter.py input.wav -o output.lab -s 2dfmc -b sf

Version 4

C-NMF for boundaries and 2D-FMC for labels. To run:

./segmenter.py input.wav -o output.lab -s 2dfmc
