传统上从法线图或梯度图进行从梯度的表面重建(Surface-from-Gradients: SfG)有很多不方面的地方, 例如难以恢复表面锐利的物体, 容易受到噪声干扰, 对不规则的感兴趣区域(ROI)的重建不理想. 为了做到对噪声复杂的图形也能正常进行重建并尽量得到好的效果, 这篇文章用一种新的方法通过对表面进行离散化处理来进行重建....

We examine the role of baroclinic instability in transferring thermal gradients from the surface of the ocean to the abyss, and thus determine the stratification. The hypothesis is that the density differences imposed at the surface by differential insolation are a large source of available potential...

Shape and surface topography evaluation from measured orthogonal slope/gradient data is of considerable engineering significance as many full-field optical sensors and interferometers readily output such a data accurately. This has applications ranging from metrology of optical and electronic elements, ...
