/*
 *  bilateral2_reg.c
 *
 *     Regression test for bilateral (nonlinear) filtering.
 *
 *     Separable operation with intermediate images at 4x reduction.
 *     This speeds the filtering up by about 30x compared to
 *     separable operation with full resolution intermediate images.
 *     Using 4x reduction on intermediates, this runs at about
 *     3 MPix/sec, with very good quality.
