A constructive model of orthogonal axonometry [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2003 A new method for object representation in arbitrary orthogonal axonometry is suggested. Constructions for a point drawing are shown, using two rotations - a rotation of the coordinate plane Oxy to the profile plane and a rotation of the profile plane to ...

Orthogonal Projections Based on Hyperbolic and Spherical n-Simplex
Advances in Mathematical Physics, 2015 Orthogonal projection along a geodesic to the chosen k-plane is introduced using edge and Gram matrix of an n-simplex in hyperbolic or spherical n-space. The distance from a point to k-plane is obtained by the orthogonal projection.

Dual‐view 3D human pose estimation without camera parameters for action recognition
IET Image Processing, 2021 The purpose of 3D human pose estimation is to estimate the 3D coordinates of key points of the human body directly from images. Although multi‐view based methods have better performance and higher precision of coordinate estimation than a single‐view ...
