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 pi, independent of image structure. We present a more general set of steerable filters that alleviate this problem.
摘要
可转向滤波器已被用于分析图像中的局部方向模式。这种滤波器通常基于方向导数，其对称性产生与图像结构无关的具有周期 pi 的周期性方向响应。我们提出了一组更通用的可转向滤波器，可缓解此问题。
