There’s gravity in higher dimensions, gravity with extra curvature terms, and gravity coupled to a ‘chameleon field’ that makes the strength of gravity different near matter than in a vacuum.
On the basis of studying the current linear and nonlinear filters for identifying potential field structure, an adaptive curvature sorting filter is designed.
