title = "Steerable wedge filters for local orientation analysis",
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 π, independent of image structure. We present a more general set of steerable filters that alleviate this problem.",

note = "Funding Information: A secondary theme in this sort of orientation analysis is that of rotation-invariance [I], [2], [4], [SI, [7]. Along these lines, Freeman and Adelson developed the concept of steerable jilters, in which an oriented filter is synthesized exactly from a linear combination Manuscript received January 13, 1995; revised September 21, 1995.
