Orthographic Pooling: Learned Maximum Intensity Projection for Vertebrae Labelling

2022 44th Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2022
Maximum intensity projection (MIP) is a standard volume-rendering technique for 3D volumetric data processing. For example, given a 3D CT data, it simply projects the voxel values with its maximum intensity on a specific view to output a 2D image. Recently, MIP is further combined with Btrfly Net for vertebrae labelling task.

Motion and structure from orthographic projections

[1988 Proceedings] 9th International Conference on Pattern Recognition, 1989
The authors review S. Ullman's (1979) results on deriving motion and structure from orthographic views. They present two further results: they show that two orthographic views allow an unresolvably infinite number of solutions for the motion/structure of a rigid body; and they give a linear algorithm for solving for motion/structure from four-point ...

Motion estimation under orthographic projection

IEEE Transactions on Robotics and Automation, 1991
Some new results for the problem of motion estimation under orthographic projection are presented. Some basic results obtained by previous researchers are refined and more detailed and precise results are provided. It is shown that, in the two-view problem, when the rotation is around the optical axis, the motion (but not the structure) is uniquely ...

Temporal phase unwrapping using orthographic projection

Optics and Lasers in Engineering, 2017
This paper proposes a novel temporal phase unwrapping method which is a generalization of the three commonly proposed approaches: hierarchical, heterodyne, and number theoretical phase unwrapping. The proposed unwrapping method is based on the orthographic projection of wrapped phases from the measurement space to the space of co-dimension 1.

Demonstrating Orthographic Projection

Technical Education and Industrial Training, 1960
Teachers of technical drawing often find difficulty in conveying the positioning, meaning and understanding of orthographic projection. This is not surprising since a solid object has to be portrayed in a certain accepted manner on a plane surface. The use of the terms ‘1st and 3rd angle’ or ‘British and American’ confuses matters, while auxiliary ...
