As soon as your photon interacts with a realistic scene (thermal), I believe it loses coherence with any apparatus you might have prepared in the detector. In short, no, I don't think this is possible, unless you consider idealized env

Intuition tells me variable extrusion generally should yield stronger parts. Adhesion between stair-stepped and non-planar layers in this method is probably subpar (with the emergence of new gaps). With variable extrusion, as long as the va

The use of hyperbolic space to encode hierarchies is absolutely genius (in not small part because it should be obvious), given the properties of hyperbolic space to "expand" around fixed points exponentially, exactly like trees do

The first versions used what you might call 'camerahack', it just sees the entire map at once but as the player himself would see (i.e. fog of war included). The latest version has camera control, only seeing one screen at a time

Emissivity is mostly what matters in this case. Whether the material is reflective or transmissive just means you'll be "seeing" IR sources reflected off the target or from behind the target, respectively. You do have to keep

Indeed, but note it usually works well enough, because most surfaces have high IR emissivity (in particular with organics like plastics, papers, woods, fabrics, etc.; soils and liquids as well). The one exception you have to be careful is w

Yea some state of the art results are just inaccessible without large budgets, simply because models can scale (and because some orgs have a lot of money to train those scaled models). You can always just use smaller models and/or lowe

I don't see any figures comparing the error of the formula with the previous error from numerical methods. While mathematically the discovery seems significant, it isn't clear to me this will actually improve lenses.
