Finally, I uploaded the code and an example on how to use the code on code.google.com. You can access the C, CUDA-C, and MATLAB interface to CUDA-C. I am going to add some more documentation.
Just one note on MATLAB interfaces. You most probably need to first go to cu_src sub directory and issue make on your own system prior to using MATLAB interface. This will update the PTX files. I just briefly tested the MATLAB interface. It is faster than the Pure MATLAB version of SEBS. However, it is not as fast as CUDA-C version, once it is executed outside MATLAB. (well, it was expected to be like this anyway).
The code project is available on:

and the download instruction is on:
