The coefficients in the *.foe files have been obtained by extracting the

matrices from the MATLAB files and performing matrix multiplication.

The format of the files is ASCII:

  <s = filter size> <K = number of filters>

  <alpha_1> ... <alpha_K>

  <f_1,1> ... <f_1,s^2>

  ...

  <f_K,1> ... <f_K,s^2>
