Difference-map algorithm — Iterations 0, 100, 200, 300 and 400 in the difference map reconstruction of a grayscale image from its Fourier transform modulus The difference map algorithm is a search algorithm for general constraint satisfaction problems. It is a meta… … Wikipedia
Difference map algorithm — The difference map algorithm is a search algorithm for general constraint satisfaction problems. It is a meta algorithm in the sense that it is built from more basic algorithms that perform projections onto constraint sets. From a mathematical… … Wikipedia
Finite difference — A finite difference is a mathematical expression of the form f(x + b) − f(x + a). If a finite difference is divided by b − a, one gets a difference quotient. The approximation of derivatives by finite differences… … Wikipedia
