摘要
从正交可分离的思想出发,提出方向滤波器的外积窗函数设计法、卷积镶边设计法和切此雪夫最优准则设计法。实验证明这些方法的有效性,并在视觉信息处理中得到应用。
This paper presents some methods of designing two- dimensional direction filters. Based on the idea of orthogonal separable filtering, three design methods of direction filter have been proposed: outer product window method, convolution edging method and Chebyshev optimal criterion method. Experments have proved the effectiveness of all these methods.
