This is primarily done for one of two reasons – levelling uneven sections of an image such as half an image ...
Perspective distortion. Simulation showing how adjusting the angle of view of a camera, while varying the camera's distance and keeping the object in frame, results in vastly differing images. At narrow angles and long distances, light rays are nearly parallel, resulting in a "flattened" image. At wide angles and short distances, objects appear ...
Aerial photographs can be used to identify different rock types on the rock exposure and the arrangement of the geological structures. [1] [5] These structures are produced by deformation processes during tectonic movement, such as faults and folds. Geologists identify different geological features and structures based on photo-lineaments.
The picture superiority effect refers to the phenomenon in which pictures and images are more likely to be remembered than are words. [2][3][4][5][6][7] This effect has been demonstrated in numerous experiments using different methods. It is based on the notion that "human memory is extremely sensitive to the symbolic modality of presentation ...
