Second-order Gaussian directional derivative representations for image high-resolution corner detection 事件

Second-order Gaussian directional derivative representations for image high-resolution corner detection arXiv:2601.08182v2 Announce Type: replace Abstract: Corner detection is widely used in various computer vision tasks, such as image matching and 3D reconstruction. Our research indicates that there are theoretical flaws in Zhang et al.'s use of a simple corner model to obtain a series of corner characteristics, as the grayscale information of two adjacent corners can affect each other.
