Having trouble get the demo work

[GekTo]

Following the instruction of the README.md,

bash
git clone https://github.com/prittjam/repeats
cd repeats
matlab -nosplash -nodesktop -r demo

It doesn't work any more.
Could you please give more detail instructions? Especially the CVPR 2014 demo, many thanks!
