A simple smiley. This is a list of emoticons or textual portrayals of a writer's moods or facial expressions in the form of icons.Originally, these icons consisted of ASCII art, and later, Shift JIS art and Unicode art.
Unicode 16.0 specifies a total of 3,790 emoji using 1,431 characters spread across 24 blocks, of which 26 are Regional indicator symbols that combine in pairs to form flag emoji, and 12 (#, * and 0–9) are base characters for keycap emoji sequences.
Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that a linear map g from V to V is well defined by the equation () = (); here, as usual, the subtraction of two points denotes the free vector from the second point to the first one, and "well-defined" means that ...
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.
Equivalently, affine shape adaptation can be accomplished by iteratively warping a local image patch with affine transformations while applying a rotationally symmetric filter to the warped image patches. Provided that this iterative process converges, the resulting fixed point will be affine invariant.
These emoji modifiers can be used on emojis that represent people or body parts including the 54 human emojis in the Miscellaneous Symbols and Pictograph block. [5] In August 2014, Peter Edberg of Apple Inc. and Mark Davis of Google proposed implementing these "emoji modifiers" to provide better representation of "human diversity" in emoji ...
