  摘要: 方向估计的主要目的是计算出图像等多维信号各点的方向信息，在图像处理和机器视觉的底层处理中具有广泛的应用。在总结现有的方向估计方法的基础上，对现有方法进行了误差比较，从而有利于对这类方法进行深入研究或设计更准确的方向估计方法。 Orientation estimation aims to compute the orientation angles of multi-dimensional signals and can be applied to many basic tasks in image processing and computer vision. In this paper, a short review of existing methods for estimating local orientation tensors has been given and error comparison was done to facilitate further research work and to design more accurate orientation estimation methods.
