Convex Non-Convex Segmentation over Surfaces
2017The paper addresses the segmentation of real-valued functions having values on a complete, connected, 2-manifold embedded in \({{\mathbb {R}}}^3\). We present a three-stage segmentation algorithm that first computes a piecewise smooth multi-phase partition function, then applies clusterization on its values, and finally tracks the boundary curves to ...

Convex Functionals on Convex Sets and Convex Analysis
1985Over the last 20 years, parallel to the theory of monotone operators, a calculus for the investigation of convex functionals designated by convex analysis has emerged, which allows one to solve a number of problems in a simple way. To this calculus belong: (α) The subgradient ∂F (a generalization of the classical concept of derivative).

Convexity with convex combinations
Antarctica Journal of Mathematics, 2013The paper refers to convexity in the space using the vector algebra supported with the geometrical images. The work relies on the properties of the basic convex sets in the plane and space, polygons and polyhedra. The well-known results are presented by using the convex and affine combinations.
