004.93A mechanism of shape recovery when the light is reflected from a surface is considered. Shape-from-shading recovery is shown to be possible for both diffuse and mirror reflections. Minimization methods are proposed to use to improve the mirror reflection algorithm.
The use of the perturbation operator to construct new modifications of Newton's method for solving minimization problems, in particular the Ulm method of split differences, Steffensen's method, is considered. and as a result of its work we obtain a sequence of points that converge to the solution point.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
