  3. Monospaced font - Wikipedia

    en.wikipedia.org/wiki/Monospaced_font

    Optical character recognition has better accuracy with monospaced fonts. Examples are OCR-A and OCR-B. The term modern is sometimes used as a synonym for monospace generic font family. The term modern can be used for a fixed-pitch generic font family name, which is used in OpenDocument format (ISO/IEC 26300:2006) and Rich Text Format. [3] [4]

  4. Esri grid - Wikipedia

    en.wikipedia.org/wiki/Esri_grid

    The binary format is widely used within Esri programs, such as ArcGIS, while the ASCII format is used as an exchange, or export format, due to the simple and portable ASCII file structure. The grid defines geographic space as an array of equally sized square grid points arranged in rows and columns.

  5. MATLAB - Wikipedia

    en.wikipedia.org/wiki/MATLAB

    MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities.

  6. Run-length encoding - Wikipedia

    en.wikipedia.org/wiki/Run-length_encoding

    Run-length encoding compresses data by reducing the physical size of a repeating string of characters. This process involves converting the input data into a compressed format by identifying and counting consecutive occurrences of each character. The steps are as follows: Traverse the input data.

  7. World file - Wikipedia

    en.wikipedia.org/wiki/World_file

    Graphical view of world files parameters and computed values of the four first upper left pixels of an image. The generic meaning of the six parameters in a world file (as defined by Esri [1]) is: Line 1: A: pixel size in the x-direction in map units/pixel; Line 2: D: rotation about y-axis; Line 3: B: rotation about x-axis

  8. MrSID - Wikipedia

    en.wikipedia.org/wiki/MrSID

    MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database.It is a file format (filename extension.sid) developed and patented [2] [3] by LizardTech (in October 2018 absorbed into Extensis) [4] for encoding of georeferenced raster graphics, such as orthophotos.

  9. Voxel - Wikipedia

    en.wikipedia.org/wiki/Voxel

    Voxel is an image of a three-dimensional space region limited by given sizes, which has its own nodal point coordinates in an accepted coordinate system, its own form, its own state parameter that indicates its belonging to some modeled object, and has properties of modeled region.
