A Simple Affine-Invariant Spline Interpolation over Triangular Meshes
Mathematics, 2022 Given a triangular mesh, we obtain an orthogonality-free analogue of the classical local Zlámal–Ženišek spline procedure with simple explicit affine-invariant formulas in terms of the normalized barycentric coordinates of the mesh triangles.

Hybrid Modulation for Modular Voltage Source Inverters with Coupled Reactors
Energies, 2020 This paper proposes and discusses a concept of a hybrid modulation for the control of modular voltage source inverters with coupled reactors. The use of coupled reactors as the integrating elements leads to significant reduction in the size and weight of

Orthorectification of Skin Nevi Images by Means of 3D Model of the Human Body
Sensors, 2021 Melanoma is the most lethal form of skin cancer, and develops from mutation of pigment-producing cells. As it becomes malignant, it usually grows in size, changes proportions, and develops an irregular border. We introduce a system for early detection of

Barycentric Coordinates as Interpolants
CoRR, 2013 Barycentric coordinates are frequently used as interpolants to shade computer graphics images. A simple equation transforms barycentric coordinates from screen space into eye space in order to undo the perspective transformation and permit accurate interpolative shading of texture maps. This technique is amenable to computation using a block-normalized

Can interestingness measures be usefully visualized?
International Journal of Applied Mathematics and Computer Science, 2015 The paper presents visualization techniques for interestingness measures. The process of measure visualization provides useful insights into different domain areas of the visualized measures and thus effectively assists their comprehension and selection ...

UBVH: Unified Bounding Volume and Scene Geometry Representation for Ray Tracing
Computer Graphics Forum, EarlyView.Abstract Bounding volume hierarchies (BVHs) are currently the most common data structure used to accelerate ray tracing. The existing BVH methods distinguish between the bounding volume representation associated with the interior BVH nodes and the scene geometry representation associated with leaf nodes.
