本文介绍了一种角点真实位置和方向的检测算子。它的实力，在处理交界处以及角落证明。利用该方法，角点被检测为沿沿着几个方向各向异性的强度图案。分析属于检测到的角的臂的像素，并且直方图搜索提供了它们的主导方向的测量。基于Yang等人提出的单导数方案[Structure adaptive anisotropic image filtering，Image and Vision Computing 14（1996）135-145]，该方法已被证明对噪声不敏感，并已被应用于合成图像和真实图像。
This paper introduces an operator for the detection of the true location and orientation of corners. Its strength in dealing with junctions as well as corners is demonstrated. With this method, corner points are detected as intensity patterns that are anisotropic along several directions. Pixels belonging to the arms of the detected corners are analysed, and a histogram search provides a measure of their dominant orientations. Based on a single derivative scheme proposed by Yang et al. [Structure adaptive anisotropic image filtering, Image and Vision Computing 14 (1996) 135–145] the approach has proved to be insensitive to noise and has been applied to both synthetic and real-life images.
