Efficient design of 2-D nonseparable filters of low complexity
By using Semi-Definite Programming (SDP) as a tool, a new deign for Two-Dimensional (2-D) Diamond-Shaped (DS) filters is developed. Surprisingly, the diamond shape of the filter is...

2-D two-fold symmetric circular shaped filter design with homomorphic processing application
A design method of a linear-phased, two-dimensional (2-D), twofold symmetric circular shaped filter is presented in this paper. Although the proposed method designs a non-separab...
