71Robust real-time object detection — The Viola and Jones Object Detection Framework is the first object detection framework to provide competitive object detection rates in real time. [ [http://research.microsoft.com/ viola/Pubs/Detect/violaJones IJCV.pdf Viola, Jones: Robust Real… …
72General number field sieve — In number theory, the general number field sieve (GNFS) is the most efficient classical algorithm known for factoring integers larger than 100 digits. Heuristically, its complexity for factoring an integer n (consisting of log2 n bits) is of …
73F-number — In optics, the f number (sometimes called focal ratio, f ratio, or relative aperture [Smith, Warren Modern Lens Design 2005 McGraw Hill] ) of an optical system expresses the diameter of the entrance pupil in terms of the focal length of the lens; …

75Colossally abundant number — In mathematics, a colossally abundant number (sometimes abbreviated as CA) is a natural number that, in some rigorous sense, has a lot of divisors. Formally, a number n is colossally abundant if and only if there is an ε > 0 such… …
76I Am Number Four — This article is about the novel. For the feature film based on this book, see I Am Number Four (film). I Am Number Four   …
77Practical number — In mathematics, and in particular number theory, a practical number or panarithmic number is a positive integer n such that all smaller positive integers can be represented as sums of distinct divisors of n . For example, 12 is a practical number …
78Embree-Trefethen constant — In number theory, the Embree Trefethen constant is a threshold value labelled β* .For a fixed real β, consider the recurrence x {n+1}=x n pm eta x {n 1} where the sign in the sum is chosen at random for each n independently with equal… …
