The *.foe files contain coefficients provided by Stefan Roth, who agreed to release them under a BSD license. See his home page: 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>
