Projective Skip-Connections for Segmentation Along a Subset of Dimensions in Retinal OCT [PDF]
International Conference on Medical Image Computing and Computer-Assisted Intervention, 2021 In medical imaging, there are clinically relevant segmentation tasks where the output mask is a projection to a subset of input image dimensions. In this work, we propose a novel convolutional neural network architecture that can effectively learn to ...

Linear and projective connections over a smooth manifold
Дифференциальная геометрия многообразий фигур, 2023 The principal bundles of the first order coframes and the second order coframes, as well as factor bundle of centroprojective (coaffine) coframes are considered.

he deformation pseudotensor of connections in cocongruence K (n - m)m
Дифференциальная геометрия многообразий фигур, 2023 The Grassmann manifold is the set of all -dimensional planes of an -dimensional projective space, with dim. One of the submanifolds of the Grassmann manifold is a complex of -planes if the dimension of the complex exceeds the difference .

Dark energy from dynamical projective connections [PDF]
Classical and quantum gravity, 2019 We further develop the gravitational model, Thomas-Whitehead gravity (TW Gravity), that arises when projective connections become dynamical fields. TW Gravity has its origins in geometric actions from string theory where the TW projective connection ...

Projective spacetime symmetry of spacetime crystals
Communications Physics, 2023 Wigner’s seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counterparts of the Poincaré group could be the spacetime groups of periodically ...

MEASURING IN IMAGES WITH PROJECTIVE GEOMETRY [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018 There is a fundamental relationship between projective geometry and the perspective imaging geometry of a pinhole camera. Projective scales have been used to measure within images from the beginnings of photogrammetry, mostly the cross-ratio on a ...

Generalized Affine Connections Associated with the Space of Centered Planes
Mathematics, 2021 Our purpose is to study a space Π of centered m-planes in n-projective space. Generalized fiberings (with semi-gluing) are investigated. Planar and normal affine connections associated with the space Π are set in the generalized fiberings.

$Y$ -meshes and generalized pentagram maps [PDF]
Discrete Mathematics & Theoretical Computer Science, 2015 We introduce a rich family of generalizations of the pentagram map sharing the property that each generates an infinite configuration of points and lines with four points on each line.

Emergent quantum state designs and biunitarity in dual-unitary circuit dynamics [PDF]
Quantum, 2022 Recent works have investigated the emergence of a new kind of random matrix behaviour in unitary dynamics following a quantum quench. Starting from a time-evolved state, an ensemble of pure states supported on a small subsystem can be generated by ...
