+ Lambertian surfaces are a special type of Matt surface. They reflect
+ light in all directions equally. They have only one parameter, the
+ amount of energy that is absorbed/re-emitted.
+
+ [[../images/adelson-checkerboard.jpg]]
+ #+caption: Lol checkerboard illusion.
+
+ Look into Helmholtz' stuff, it might be interesting. It was the
+ foundation of both vision and audition research. Seems to have took
+ a sort of Baysean approach to inferring how vision/audition works.
+
+ - Homomorphic filtering :: Oppenhiem, Schafer, Stockham, 1968. also
+ look at Stockham, 1972.
+
+ Edwin Land was Adelson's hero back in the day. He needed to create a
+ color photo for the Polaroid camera. In order to process for
+ automatic development of film, he had to get a good approximation for
+ the illumination/reflectance decomposition that humans do, which he
+ called Retinex.
+
+ Cornsweet square wave grating is cool.
+
+ - Retinex :: use derivatives to find illumination. Sort of
+ implicitly deals with edges, etc. Can't deal with
+ non-lambertian objects.
+
+
+ Adelson introduces the problem as an "inverse" problem, where you
+ try to "undo" the 3-d projection of the world on your retina.
+
+ On the functional view of vision : "What it takes" is to build a
+ model of the world in your head. The bare minimum to get success in
+ life is to have a model of the world. Even at the level of a single
+ cell, I think you still benefit from models.
+
+ Spatial propagation is ABSOLUTELY required to separate embossed
+ stuff from "painted" stuff. Edges, likewise, MUST have spatial
+ context to disambiguate. The filters we use to deal with edges must
+ have larger spatial context to work, and the spatial extent of this
+ context must be the ENTIRE visual field in some cases!
+
+------------------------------------------------------------
+
+** Illumination, shape, reflectance all at once
+
+ What if we tried to infer everything together? Some images are so
+ ambiguous it requires propagation from all three qualities to
+ resolve the ambiguity.
+
+ Brain has a competing painter, sculptor, and gaffer which each try
+ to "build" the things in the world. There is a cost to everything
+ such as paints, lights, and material, and then you try to optmize
+ some cost function using these primitives.
+
+
+ Horn, technical report, 1970

-* COMMENT Ethical Considerations Regarding DARPA's Mind's Eye Program
-
-As scientists and engineers, it is our sacred duty to explore the
-boundaries of human knowledge in a responsible way. We are part of the
-larger organism of humanity, and tasked with discovering new things
-that help the race first, and all life second.
-
-While knowledge and non-sentient technology is neither morally good or
-evil, the things we discover are embedded in a wider cultural context,
-and in many cases it is possible to foresee possible uses and abuses
-our new technology will enable.
-
-It is naive to think that the government or any group of humans is
-either wholly good or evil, but by reasoning from the
-motivations/power of such groups, we can try to infer whether a
-technology will improve the lot of humanity or not.
-
-It is possible to give and institution/culture a technology that they
-will enthusiastically accept, but which will greatly diminish their
-quality of life.
-
-Some examples:
-
-PGP -- an encryption suite that can help individuals to send messages
-
-
-
-* Questions
-
-- What should our ethical place be in deciding whether or not to
- pursue research?
-
- - Follow orders, assume our overall culture will use things
- responsibly, and leave the ethical considerations to the
- government/people.
-
- - Many scientists who worked on the atomic bomb later questioned
- their decisions.
- - Yet, an advanced society /should/ have atomic weapons, if for
- nothing else than to defend themselves from meteors, blow shit
- up, etc.
-
- - We are each morally responsible for the things we help create. We
- are responsible for the misuses of technology we develop and the
- pain and suffering it causes. Ultimately our contributions to
- society will be judged by whether our technology did more good
- than bad.
-
-- If we decide that we *are* morally responsible for the technology we
- develop, then is the Mind's Eye project in particular something we
- should be doing?
-
- - Here are some things you can build with Mind's Eye tech:
-
- - System to monitor single humans living alone and call for help
- in the case of emergencies (such as a fall)
-
- - Same system for hospitals and nursing homes (of course, this
- also makes them even more impersonal)
-
- - The equivalent of a FBI special agent watching everything you do
- from the moment you step out your door to the moment you go back
- to your house to sleep, building a dossier of every move you
- make, everyone you talk to, where you shop, etc.
-
- - A concentration camp / prison that is ABSOLUTELY impossible to
- escape from.
-
- - Many other countries that don't care as much about human rights
- as America will use this technology to monitor their citizens
- 24/7.
-
- - Protection from surveillance in you own home does not apply
- unless you *own* your house. Say goodbye to privacy in school
- dorms, apartments, rented houses, etc.
-
- - People are OK with current surveillance because it is
- *dumb*. Mostly people only use security camera footage in the case
- of crimes, and it is a painstaking process because it requires
- manual human intervention. With AI, this will soon not be the
- case.
