function p = foe_5_24() %foe_5_24 5x5 FoE model with 24 filters % P = FOE_5_24() returns a struct P of an FoE model with 3 or 4 fields: % - P.dims contains the size of the filters (e.g. [5, 5].) % - P.alpha is a vector of expert parameters. Its length determines the % number of experts. % - P.J contains a matrix of filters, where each column contains the % filter corresponding to a particular expert. % - P.basis (optional) contains the basis in which the filter coefficients % are defined. The filters as they apply to the unmodified pixels can be % obtained from the product of P.basis' * P.J. % % Author: Stefan Roth, Department of Computer Science, Brown University % Contact: [email protected] % Date: 06/07/2005 % Copyright 2004,2005, Brown University, Providence, RI. % % All Rights Reserved % % Permission to use, copy, modify, and distribute this software and its % documentation for any purpose other than its incorporation into a % commercial product is hereby granted without fee, provided that the % above copyright notice appear in all copies and that both that % copyright notice and this permission notice appear in supporting % documentation, and that the name of Brown University not be used in % advertising or publicity pertaining to distribution of the software % without specific, written prior permission. % % BROWN UNIVERSITY DISCLAIMS ALL WARRANTIES WITH REGARD TO THIS SOFTWARE, % INCLUDING ALL IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR ANY % PARTICULAR PURPOSE.
