Is there a relation between the Hessian matrix and the structure Tensor?
begin{pmatrix} \frac{\partial^2 I}{\partial x^2}&\frac{\partial^2 I}{\partial x \partial y}\\ \frac{\partial^2 I}{\partial x \partial y}&\frac{\partial^2 I}{\partial y^2} \end{pmatrix}$ and the structure tensor … As far as i know, the structure tensor is also called "autocorrelation matrix" or "second moment matrix".
I am using these two matrices to find so called "interesting points" in an image. …
