A new design for linear phase diamond-shaped (dS) and circular-shaped (CS) 2-d filters is developed. First, the frequency masks are efficiently constrained by 2-dsecond-ordertrigonometricpolynomials. Then semi-definite program ming (SdP) of reasonably low dimension is employed to effectively express the filter specifications. Several numerical examples are provided to demonstrate the superior performance of our design in comparison with all other existing designs.
