A new design method for linear phase half-band diamond (DS) and fan-shaped (FS) 2-D filters is proposed. A general formulation for frequency mask constraints in different shapes using 2-D trigonometric curves is developed. This facilitates semi-definite programming (SDP) of moderate dimension for the design problem. Several examples are included to illustrate advantages of our method. © 2007 IEEE.
