摘要
取向是多维信号区别于一维信号的基本特征之一,取向估计在图像信息处理和计算机视觉的许多领域都有直接应用。提出了一种新的取向估计方法,该方法将频域滤波和主元分析法相结合,提高了估计结果的精度及鲁棒性。实验结果及分析表明该方法的优越之处。
Local orientation is a feature of multi-dimensional signals, Orientation estimation play an important role in many image processing and computer vision tasks. This paper presents a method for orientation estimation, which is based on combination of two already well known techniques： signal filtering in Fourier domain with principle component analysis. As experimental results show, this method enjoy excellent precision and robustness. Both simulated and real image examples are presented to demonstrate the proposed method.
