  2. CBOR - Wikipedia

    en.wikipedia.org/wiki/CBOR

    Because nested items may also use the indefinite encoding, the parser must pair the break markers with the corresponding indefinite-length header bytes. Type 5 is similar but encodes a map (also called a dictionary, or associative array) of key/value pairs. In this case, the count encodes the number of pairs of items. If the indefinite-length ...

  3. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    Graphs of maps, especially those of one variable such as the logistic map, are key to understanding the behavior of the map. One of the uses of graphs is to illustrate fixed points, called points. Draw a line y = x (a 45° line) on the graph of the map. If there is a point where this 45° line intersects with the graph, that point is a fixed point.

  4. Semi-global matching - Wikipedia

    en.wikipedia.org/wiki/Semi-global_matching

    Semi-global matching (SGM) is a computer vision algorithm for the estimation of a dense disparity map from a rectified stereo image pair, introduced in 2005 by Heiko Hirschmüller while working at the German Aerospace Center. [1]

  5. Map matching - Wikipedia

    en.wikipedia.org/wiki/Map_matching

    Map matching is the problem of how to match recorded geographic coordinates to a logical model of the real world, typically using some form of Geographic Information System. The most common approach is to take recorded, serial location points (e.g. from GPS ) and relate them to edges in an existing street graph (network), usually in a sorted ...

  6. Conformal geometric algebra - Wikipedia

    en.wikipedia.org/wiki/Conformal_geometric_algebra

    The point x = 0 in R p,q maps to n o in R p+1,q+1, so n o is identified as the (representation) vector of the point at the origin. A vector in R p +1, q +1 with a nonzero n ∞ coefficient, but a zero n o coefficient, must (considering the inverse map) be the image of an infinite vector in R p , q .

  7. Comparison of data-serialization formats - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_data...

    ^ ASN.1 has X.681 (Information Object System), X.682 (Constraints), and X.683 (Parameterization) that allow for the precise specification of open types where the types of values can be identified by integers, by OIDs, etc. OIDs are a standard format for globally unique identifiers, as well as a standard notation ("absolute reference") for ...

  8. Perfect hash function - Wikipedia

    en.wikipedia.org/wiki/Perfect_hash_function

    Computing the hash value of a given key x may be performed in constant time by computing g(x), looking up the second-level function associated with g(x), and applying this function to x. A modified version of this two-level scheme with a larger number of values at the top level can be used to construct a perfect hash function that maps S into a ...

  9. Conformal map - Wikipedia

    en.wikipedia.org/wiki/Conformal_map

    In mathematics, a conformal map is a function that locally preserves angles, but not necessarily lengths. More formally, let U {\displaystyle U} and V {\displaystyle V} be open subsets of R n {\displaystyle \mathbb {R} ^{n}} .
