	I am trying to implement an adaptive filter (joint process estimator/
noise canceller) on two gray scale images. I'd prefer to use IDL over C or 
Fortran. Ideally (no pun intended), I'd like to use a two-dimensional filter
rather than run a pure raster scan a pixel at a time over the image. Does anyonehave any experience at implementing a 2D sliding window moving over a larger
matrix in IDL? Any related experiences? We are especially interested in ARMA-
type estimators, and lattice or fast transversal RLS algorithms.
