A Creative Genius for VisionVisual IntelligenceDonald D. Hoffman Chapter One The Genius of VisionEverything you see, you constructOur visual prowess is a genius that often goes unrecognizedYet, we construct scenes that contradict reality Is our vision or our hand erroneous?Can there be elements in the picture causing the problem?

More Evidence The Magic SquareBrighter inside is a vision or photometer error?Ironically, the boundary increase makes the construction of the square difficult

More EvidenceVision can do more than fabricate a structure, as it goes against realityWe build a triangle, even though this could be a structure photographed at a specific angle

The Devils Triangle

What you seeThere are elegant principles being applied when constructing an imagePhenomenal sense The way things appear to us, objects we construct regardless of reality constraintsRelational sense what you interact with when you see, things must exist to be seenThe phenomenal sense applies to our visual geniusVisual experiences serve as user-friendly computer icon interface with those things we relationally see

Vision Comes NaturallyUnlike the ability to walk or talk, humans can see upon birth It is also an ability that we share with animals alikeGold fish have four color receptorsHoneybees see ultraviolet lightIs our vision the correct vision?

A Childs Visual DevelopmentOne month infants blink if something moves toward their eyes3 months infants use visual motion to construct boundaries of objects4 months use motion and stereovision to construct 3D shapes of objects7 months use shading, perspective, and interposition to construct depth and shapeOne year visual geniuses that begin to learn the name of objectsVisual Construction in NatureFor some species, their visual construction displays less geniusBut no different than humans, this leaves room for visual errorsBlackbird Nestlings

Brief HistoryPtolemy (2nd century AD) recognized in Optics is a dictate of logic

Alhazen (965-1039) visual properties due to unconscious inference

Nicolas Malebranche (1638-1715) visual inferences came God

A Brief HistoryHermann von Helmholtz (1821-1894) described vision as a process of unconscious inference

David Marr (1946-1981) compared visual construction to information processing in computers

Ernst Hans Gombrich(1909) unconscious and automatic processes are projections, while those that are more labored for are inference or knowledge

Fundamental Problem of VisionThe image at the eye has countless interpretationsHow can we know that we all see the same thing?Innate rules which grant visual mastery and lead to consensus in the visual constructions despite ambiguityEveryone constructs the same vision (with or without the same interpretation)The rules, which work quickly and effectively are the key
