  3. Boolean operations on polygons - Wikipedia

    en.wikipedia.org/wiki/Boolean_operations_on_polygons

    Modern implementations for Boolean operations on polygons tend to use plane sweep algorithms (or Sweep line algorithms). A list of papers using plane sweep algorithms for Boolean operations on polygons can be found in References below. Boolean operations on convex polygons and monotone polygons of the same direction may be performed in linear ...

  4. Connected-component labeling - Wikipedia

    en.wikipedia.org/wiki/Connected-component_labeling

    A counter is initialized to count the number of objects. A row-major scan is started for the entire image. If an object pixel is detected, then following steps are repeated while (Index !=0) Set the corresponding pixel to 0 in Image. A vector (Index) is updated with all the neighboring pixels of the currently set pixels.

  5. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    This is sometimes called an inverse mask or a wildcard mask. When the value of the mask is broken down into binary (0s and 1s), the results determine which address bits are to be considered in processing the traffic. A 0-bit indicates that the address bit must be considered (exact match); a 1-bit in the mask is a "don't care". This table ...

  6. Logical matrix - Wikipedia

    en.wikipedia.org/wiki/Logical_matrix

    A logical matrix, binary matrix, relation matrix, Boolean matrix, or (0, 1)-matrix is a matrix with entries from the Boolean domain B = {0, 1}. Such a matrix can be used to represent a binary relation between a pair of finite sets. It is an important tool in combinatorial mathematics and theoretical computer science.

  7. Data masking - Wikipedia

    en.wikipedia.org/wiki/Data_masking

    Data masking or data obfuscation is the process of modifying sensitive data in such a way that it is of no or little value to unauthorized intruders while still being usable by software or authorized personnel. Data masking can also be referred as anonymization, or tokenization, depending on different context.

  8. Boolean - Wikipedia

    en.wikipedia.org/wiki/Boolean

    Boolean domain, a set consisting of exactly two elements whose interpretations include false and true; Boolean circuit, a mathematical model for digital logical circuits. Boolean expression, an expression in a programming language that produces a Boolean value when evaluated; Boolean function, a function that determines Boolean values or operators

  9. Symmetric Boolean function - Wikipedia

    en.wikipedia.org/wiki/Symmetric_Boolean_function

    In mathematics, a symmetric Boolean function is a Boolean function whose value does not depend on the order of its input bits, i.e., it depends only on the number of ones (or zeros) in the input. [1] For this reason they are also known as Boolean counting functions. [2] There are 2 n+1 symmetric n-ary Boolean functions.
