The field of projection methods is vast; see, e.g., Bauschke and Borwein [27], Combettes [28], Combettes and Pesquet [29].
We spoke to the projection mapping artist about her creative process, her beginnings in the field of projection mapping, and how she earned permission from the Presidency of France to incorporate the Eiffel Tower into her work.
After large injections of retrograde tracers, earlier investigations reported a very widespread field of projection neurons in posterior visual areas (Morel and Bullier 1990; Baizer et al. 1991; Webster et al. 1991).
The "SPICE" system1 has been widely used since the days of the Magellan mission to Venus as the method for scientists and engineers to access a variety of space mission geometry such as positions, velocities, directions, orientations, sizes and shapes, and field-of-view projections (Acton, 1996).
For surface visualizations, a simple formula is presented calculating the normal vector field of the projection of Γ into R3, which gives light shadings.
With MGNTRN (pronounced "Magnotron"), French new-media artist Romain Tardy has pushed the limits of video mapping by transforming a giant ferris wheel and its surrounding environment into a field of dynamic projection mapping.
In this case, the application of an implementation of the filtered back projection (FBP) algorithm after the so-called flat fielding of the projection data is often proposed as a solution for the tomographic problem.
Images were acquired in list-mode with the following parameters: 50 kVp X-ray source voltage, 180 μA current, a composite X-ray filter of 0.5 mm aluminium, 120 ms camera exposure time per projection, 9 projections per view, 23 × 35 mm field of view, acquiring projections with 0.7° increments over a total angle of 180°, producing images with a real pixel size of 35 μm.
The finding is good news for the gloomy field of human population projection, but growth will have to slow substantially in developing countries if global numbers are to peak at an estimated 9 billion people.
It is of note, however, that the ipsilateral terminal field is relatively thin across most of the dLGN (∼100 μm; [ 2]) by comparison with the dendritic field of mouse thalamocortical projection neurons (∼150 μm; [ 19]).
This size dependency argues against segregation by feedback since termination fields of feedback projections cover large regions of visual space in V1.
