For similar 2D and 3D shapes, there is a relationship between the length scale factor and the area, surface area or volume of the enlarged shapes. Areas increase by a factor equivalent to the length ...

Abstract: Fourier descriptors are classical global shape descriptors with high matching speed but low accuracy. To obtain higher accuracy, a novel framework for forming Fourier descriptors is proposed ...

A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

The multimillion-dollar collaboration has shaped classroom materials used widely across the state. A review by advocacy group Comms Declare argues that key scientific explanations have been ...

Abstract: One of the valuable directions in feature based SLAM is to parameterize and estimate features accurately. In the real world, closed shape features are especially common. It is necessary to ...

Bevy Vector Shapes is in the early stages of development. You may encounter issues, but feel free to report them.

We proposed a novel neural deformable model (NDM) targeting at the reconstruction and modeling of 3D bi-ventricular shape of the heart from 2D sparse cardiac magnetic resonance (CMR) imaging data. The ...
