Depending on the resolution, the feedback is implementable and achieves the closed-loop stability of dynamical systems as long as the input-output linearity on matrix space exists. Remarkably, a part of the whole occlusion effects is rejected, and the remaining part is attenuated. The validity is confirmed by the experimental feedback for nonplanar sloshing., Article, IEEE TRANSACTIONS ON CONTROL SYSTEMS TECHNOLOGY. 27(2):2176-2187 (2019)}, pages = {864--871}, title = {Visual Feedback Without Geometric Features Against Occlusion: A Walsh Basis}, volume = {27}, year = {2019} }
