Fastdiscretecurvelettransforms
This paper describes two digital implementations of a new mathematical transform, namely,
the second generation curvelet transform [12, 10] in two and three dimensions. The first digital
transformation is based on unequally-spaced fast Fourier transforms (USFFT) while the second is
based on the wrapping of specially selected Fourier samples. The two implementations essentially
differ by the choice of spatial grid used to translate curvelets at each scale and angle. Both
digitaltransformations return a table of digital curvelet coefficients indexed by a scale
parameter, anorientation parameter, and a spatial location parameter. And both implementations are
fast in
the sense that they run in O(n2 log n) flops for n by n Cartesian arrays in addition, they are
also invertible, with rapid inversion algorithms of about the same complexity.

proiect
In this paper we present the usefulness of the algorithm DCT (Discrete cosine Transform) blocks applied level image compression JPEG (Joint Photographic Experts Goup). It has been shown that this algorithm is the most efficient in the case of compression because it has very good properties for compaction energy related values. As a basic principle we eliminate high frequencies and keep the low and medium without visibly affecting image. DCT in JPEG compression algorithm is encountered in practical applications such as face detection, skin color, facial recognition, iris, fingerprints

FuzzyPAdaptivePRobustPPIDPController
适合用来学习模糊控制的源码。模糊自适应PID效果是非常不错。PID控制器，一种工业控制方式,比例积分微分控制规律（控制器数学模型G(S)=比例＋微分＋积分）,经常用P表示比例，用I表示积分，用D表示微分。(Suitable for learning fuzzy control of the source. Fuzzy adaptive PID effect is very good. PID controller, an industrial control, PID control law (mathematical model of the controller G (S) = ratio of+ differential+ points), often expressed by P ratio, with the points I said, with the D that differential.)
