Constructing the Hessian matrix to construct the Gaussian image pyramid: First, the scale space is constructed for the input image. This usually involves constructing a pyramid of images using ...

The VTA around each electrode contact relied on the concept of activation function (AF), which was calculated from the eigenvalues of the Hessian matrix (38). Each eigenvalue of the Hessian matrix ...

Is this real life? Is this just fantasy? A growing number of scientists are suggesting that the idea that we are all living in a simulation may not be completely far-fetched. Simulation theory is ...

However, the adjoint-based migration methods may produce a blurry image, convolved by a Hessian matrix. To address this problem, we propose a Hessian-assisted iterative self-training learning (HAISTL) ...

The RF segmentation is applied to the surface density map of the adsorbed molecules and employs multiple features (intensity, gradient, and the eigenvalues of the Hessian matrix) which are nonlocal ...

The Hessian matrix conveys important information about the curvature, spectrum and partial derivatives of a function, and is required in a variety of tasks. However, computing the exact Hessian is ...

Hessian matrices are square matrices consisting of all possible combinations of second partial derivatives of a scalar-valued initial function. As such, Hessian matrices may be treated as elementary ...

Upon arrival, he quickly learned of the spookiest of all tales in Empty Interior — that of the headless Hessian matrix, a specter that roams the town, sending anyone it encounters into the heights of ...

If we calculate the hessian matrix and jacobian ourselves and use the Problem interface*, we can define their structures. Defining the hessian matrix and jacobian structures will make the solver ...
