    en.wikipedia.org/wiki/Spot_the_difference

    Description. Spot the difference games are found in various media including activity books for children, newspapers, and video games. They are a type of puzzle where players must find a set number of differences between two otherwise similar images, whether they are illustrations or photographs that have been altered with photo manipulation.

  3. Visual thinking - Wikipedia

    en.wikipedia.org/wiki/Visual_thinking

    Visual thinking, also called visual or spatial learning or picture thinking, is the phenomenon of thinking through visual processing. [1] Visual thinking has been described as seeing words as a series of pictures. [2][3] It is common in approximately 60–65% of the general population. [1] ". Real picture thinkers", those who use visual ...

  4. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    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 ...

  5. Image subtraction - Wikipedia

    en.wikipedia.org/wiki/Image_subtraction

    Image subtraction or pixel subtraction or difference imaging is an image processing technique whereby the digital numeric value of one pixel or whole image is subtracted from another image, and a new image generated from the result. This is primarily done for one of two reasons – levelling uneven sections of an image such as half an image ...

  6. Picture superiority effect - Wikipedia

    en.wikipedia.org/wiki/Picture_superiority_effect

    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 ...

  7. Boundary extension - Wikipedia

    en.wikipedia.org/wiki/Boundary_extension

    Visual memory can be defined as the process by which one encodes and remembers visual information such as pictures. Visual memory is relevant to boundary extension because boundary extension is a visual memory phenomenon where one has to rely on the visual aspects of memory to try and recall pictures or notice any changes in the pictures or scenes.

  8. Change blindness - Wikipedia

    en.wikipedia.org/wiki/Change_blindness

    Change blindness. Example of images that can be used in a change blindness task. Although similar, the two images have a number of differences. Change blindness is a perceptual phenomenon that occurs when a change in a visual stimulus is introduced and the observer does not notice it. For example, observers often fail to notice major ...

  9. Comparison of digital and film photography - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_digital_and...

    However, even if both techniques have inherent noise, it is widely appreciated that for color, digital photography has much less noise/grain than film at equivalent sensitivity, leading to an edge in image quality. [10] For black-and-white photography, grain takes a more positive role in image quality, and such comparisons are less valid.
