Design of FIR two- dimensional digital filters by successive projections
Ahmed Abotaleb, Moustafa M. Fahmy · IEEE Transactions on Circuits and Systems · 1984
An iterative optimization technique based on the method of successive projections is proposed for the design of the two-dimensional (2-D) linear phase FIR digital filters. The technique is simple, fast, and compares favorably with the presently available design techniques. To illustrate the method several filters with masks up to25 \times 25have been designed. The technique can also be used to design 1-D linear phase FIR filters.
