Abstract
Steerable filters have been used to analyze local orientation patterns in imagery. Such filters are typically based on directional derivatives, whose symmetry produces orientation responses that are periodic with period /spl pi/, independent of image structure. We present a more general set of steerable filters that alleviate this problem.Keywords
