Affine phase 2-D filters are designed using the p/sup th/ power norm to measure its deviation from an idealized affine phase filter response not necessarily symmetric. Necessary and sufficient conditions are derived in terms of its coefficients for the filter to be affine phase. The 2-D design is obtained in closed form for p=2. Next the design is generalized for 2
