BRISK and FREAK descriptors in MATLAB

Question

I'm using MATLAB 2014a for extracting BRISK and FREAK descriptors. I couldn't find any option to reduce the bit string size to 128 or 256, they both generated as 512 bits. I think FREAK does not allow this by algorithm but BRISK should allow. Does anyone know if I can reduce the dimension of BRISK descriptor? If yes how can I?

Thanks

[This](http://www.asl.ethz.ch/people/lestefan/personal/BRISK) is the official code. See if they have provided an option. — Autonomous, Aug 15 '14 at 22:43
That is official code for BRISK. [This](http://lts2www.epfl.ch/software) is official code for FREAK. — Autonomous, Aug 16 '14 at 06:09

Unfortunately the current MATLAB implementation only computes the 512 bit BRISK descriptor.
