**Error diffusion** — is a type of halftoning in which the quantization residual is distributed to neighboring pixels which have not yet been processed. Its main use is to convert a multi level image into a binary image, though it has other applications.Unlike many… … Wikipedia

**Error detection and correction** — In mathematics, computer science, telecommunication, and information theory, error detection and correction has great practical importance in maintaining data (information) integrity across noisy channels and less than reliable storage… … Wikipedia

**Algorithm** — Flow chart of an algorithm (Euclid s algorithm) for calculating the greatest common divisor (g.c.d.) of two numbers a and b in locations named A and B. The algorithm proceeds by successive subtractions in two loops: IF the test B ≤ A yields yes… … Wikipedia

**Error function** — Plot of the error function In mathematics, the error function (also called the Gauss error function) is a special function (non elementary) of sigmoid shape which occurs in probability, statistics and partial differential equations. It is defined … Wikipedia
