摘要 角点是图像的重要局部特征,通过处理图像的角点可大大减少图像处理过程中的计算量.角点检测在图像特征提取、图像配准、超分辨率重建等方面都有重要的应用;根据实现方法不同可将角点检测的方法分为三大类.指出角点检测技术的研究和发展方向. Corner is a significant local feature of images.A lot of Corner detection algorithms are based on the property corners that the changes of image intensity must be high in all directions.Corner detection is an important method of low-level image processing.Corner detection have been used in optical flow compution,motion estimate and meature of machine vision.
