Let $\Omega=\mathbb{R}^N$, let $u\in\mathrm{BV}^2(\mathbb{R}^N)$, and let $H_nu$ denote the non-local Hessian of $u$ associated with the approximation of the identity used in the p…

Let $x$ and $y$ be neighbouring points, and let $c3_x(y)$ denote the weight assigned to $y$ relative to $x$. The non-local Hessian method can produce a pixelated structure along sl…
