  2. Wormhole - Wikipedia

    en.wikipedia.org/wiki/Wormhole

    A wormhole is a hypothetical structure which connects disparate points in spacetime. It may be visualized as a tunnel with two ends at separate points in spacetime (i.e., different locations, different points in time, or both). Wormholes are based on a special solution of the Einstein field equations. [1]

  3. Non-orientable wormhole - Wikipedia

    en.wikipedia.org/wiki/Non-orientable_wormhole

    The alternative way of connecting the surfaces makes the "connection map" appear the same at both mouths. This configuration reverses the "handedness" or "chirality" of any objects passing through. If a spaceship pilot writes the word "IOTA" on the inside of their forward window, then, as the ship's nose passes through the wormhole and the ship's window intersects the surface, an observer at ...

    The wormhole metric has the proper-time form =, where = + = + (+) = + (+) [+ (⁡)] and is the drainhole parameter that survives after the parameter of the Ellis drainhole solution is set to 0 to stop the ether flow and thereby eliminate gravity.

  5. Ellis drainhole - Wikipedia

    en.wikipedia.org/wiki/Ellis_drainhole

    The Ellis drainhole is the earliest-known complete mathematical model of a traversable wormhole.It is a static, spherically symmetric solution of the Einstein vacuum field equations augmented by inclusion of a scalar field minimally coupled to the geometry of space-time with coupling polarity opposite to the orthodox polarity (negative instead of positive):

  6. Outline of object recognition - Wikipedia

    en.wikipedia.org/wiki/Outline_of_object_recognition

    Object recognition – technology in the field of computer vision for finding and identifying objects in an image or video sequence. Humans recognize a multitude of objects in images with little effort, despite the fact that the image of the objects may vary somewhat in different view points, in many different sizes and scales or even when they are translated or rotated.

  7. Visual perception - Wikipedia

    en.wikipedia.org/wiki/Visual_perception

    Visual perception is the ability to detect light and use it to form an image of the surrounding environment. [1] Photodetection without image formation is classified as light sensing. In most vertebrates, visual perception can be enabled by photopic vision (daytime vision) or scotopic vision (night vision

  9. Visual search - Wikipedia

    en.wikipedia.org/wiki/Visual_search

    Visual search is a type of perceptual task requiring attention that typically involves an active scan of the visual environment for a particular object or feature (the target) among other objects or features (the distractors). [1] Visual search can take place with or without eye movements.
