A filter design technique for steerable pyramid image transforms
Anestis Karasaridis, Eero P. Simoncelli · 2002
We describe a novel recursive filter design technique for multi-scale "pyramid" transforms. The recursion in the design technique follows that of the pyramid construction, and allows us to solve a reduced design problem at each step. We demonstrate the use of this technique by designing filters of various orientation bandwidths for use in a "steerable pyramid" image transform.
