Summary:The authors present an efficient architecture to synthesize
filters of arbitrary orientations from linear combinations of basis
filters, allowing one to adaptively steer a filter to any orientation,
and to determine analytically the filter output as a function of
orientation. Steerable filters may be designed in quadrature pairs to
allow adaptive control over phase as well as orientation. The authors
show how to design and steer the filters and present examples of their
use in the analysis of orientation and phase, angularly adaptive
filtering, edge detection, and shape from shading. One can also build a
self-similar steerable pyramid representation. The same concepts can be
generalized to the design of 3-D steerable filters
