A hybrid image (top) constructed from low-frequency components of a photograph of Marilyn Monroe (left inset) and high-frequency components of a photograph of Albert Einstein (right inset). A hybrid image is an image that is perceived in one of two different ways, depending on viewing distance, based on the way humans process visual input.
This type of photograph captures a fairly sizable region. [5] As in a low oblique photograph, the length between two points and the orientation of objects are inaccurate. [5] High oblique aerial photographs are widely used in assisting field investigation because the line of sight shown is more similar to humans. [3]
[12] [13] [14] Geographers researching communication over the past two decades have extended these research areas while carrying forward early insights regarding the importance of communication to the formation of regions, the rate of information flow as a measure of spatial interaction, and the association between landscape and representation.
Stereoscopy creates the impression of three-dimensional depth from a pair of two-dimensional images. [5] Human vision, including the perception of depth, is a complex process, which only begins with the acquisition of visual information taken in through the eyes; much processing ensues within the brain, as it strives to make sense of the raw information.
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Ambiguous images or reversible figures are visual forms that create ambiguity by exploiting graphical similarities and other properties of visual system interpretation between two or more distinct image forms. These are famous for inducing the phenomenon of multistable perception. Multistable perception is the occurrence of an image being able ...
Spatial contextual awareness can describe present context – the environment of the user at the present time and location, or that of a future context – where the user wants to go and what may be of interest to them in the approaching spatial environment. Some location-based services are proactive systems which can anticipate future context. [3]
Distance decay is a geographical term which describes the effect of distance on cultural or spatial interactions. [1] The distance decay effect states that the interaction between two locales declines as the distance between them increases. Once the distance is outside of the two locales' activity space, their interactions begin to decrease.
