2-D FIR filters design using least square error with scaling-free McClellan transformation
Hung‐Ching Lu, Kuo-Hsien Yeh · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 2000
The optimal coefficients of the scaling-free McClellan transformation and the 1-D prototype filters for the design of 2-D digital filters are designed in this brief. These 2-D filters include fan filters with arbitrary inclination, elliptically symmetric filters, elliptically symmetric filters with arbitrary orientation, circular filters and diamond-shaped filters.
