  2. Flipped image - Wikipedia

    en.wikipedia.org/wiki/Flipped_image

    A flipped image is a static or moving image that is generated by a mirror-reversal of an original across a horizontal axis, making the image upside-down. In contrast, a flopped image is mirrored across the vertical axis, as in a conventional mirror image .

  3. Flopped image - Wikipedia

    en.wikipedia.org/wiki/Flopped_image

    In photography and graphic arts a flopped image is a static or moving image that is generated by a reversal of an original image across a vertical axis, as in a conventional mirror image. This is opposed to a flipped image , which means an image reversed across a horizontal axis.

  4. Mirror image - Wikipedia

    en.wikipedia.org/wiki/Mirror_image

    In general, an object and its mirror image are called enantiomorphs. If a point of an object has coordinates (x, y, z) then the image of this point (as reflected by a mirror in the y, z plane) has coordinates (−x, y, z). Thus reflection is a reversal of the coordinate axis perpendicular to the mirror's surface.

  5. List of flags with reverses that differ from the obverse

    en.wikipedia.org/wiki/List_of_flags_with...

    Flag sides are usually mirror copy to satisfy manufacturing constraints. Identical flags are much less common and contain an element for which a simple mirror image would be problematic, such as text (e.g. The Flag of Saudi Arabia includes the shahada, an Islamic creed; The Flag of Iraq includes the Takbir) or a geographic feature (e.g.

  6. Autostereogram - Wikipedia

    en.wikipedia.org/wiki/Autostereogram

    The program tiles the pattern image horizontally to cover an area whose size is identical to the depth map. Conceptually, at every pixel in the output image, the program looks up the grayscale value of the equivalent pixel in the depth map image, and uses this value to determine the amount of horizontal shift required for the pixel.

  7. Reverse image search - Wikipedia

    en.wikipedia.org/wiki/Reverse_image_search

    Reverse image search using Google Images. Reverse image search is a content-based image retrieval (CBIR) query technique that involves providing the CBIR system with a sample image that it will then base its search upon; in terms of information retrieval, the sample image is very useful. In particular, reverse image search is characterized by a ...

  8. Image warping - Wikipedia

    en.wikipedia.org/wiki/Image_warping

    Image warping example. Image warping is the process of digitally manipulating an image such that any shapes portrayed in the image have been significantly distorted. Warping may be used for correcting image distortion as well as for creative purposes (e.g., morphing [1]). The same techniques are equally applicable to video.

  9. Anamorphic format - Wikipedia

    en.wikipedia.org/wiki/Anamorphic_format

    To increase overall image detail, by using all the available area of the negative for only that portion of the image which will be projected, an anamorphic lens is used during photography to compress the image horizontally, thereby filling the full (4 perf) frame's area with the portion of the image that corresponds to the area projected in the ...
