WebHessian matrix. In mathematics, the Hessian matrix or Hessian is a square matrix of second-order partial derivatives of a scalar-valued function, or scalar field. It describes the local curvature of a function of many variables. The Hessian matrix was developed in the 19th century by the German mathematician Ludwig Otto Hesse and later named ...

WebA keypoint-based approach to detect the copy–move forgery in an image by extracting the key points through a fast Hessian detector and using the adaptive minimal–maximal suppression (AMMS) strategy for distributing the keypoints evenly throughout an image. Expand. 2. Save. Alert. WebDec 23, 2024 · One way to make it faster is using functorch.hessian (based on this issue), however it has to recompute the loss everytime a Hessian is calculated (while I already have access to the loss).Nevertheless, i'll post it for those that are interested.
