// Histogram Sample
// This sample shows how to use the Sample Grabber filter for video image processing.
// Conceptual background:
// A histogram is just a frequency count of every pixel value in the image.
// There are various well-known mathematical operations that you can perform on an image
// using histograms, to enhance the image, etc.
// Histogram stretch (aka automatic gain control):
// Stretches the image histogram to fill the entire range of values. This is a "point operation,"
// meaning each pixel is scaled to a new value, without examining the neighboring pixels. The
// histogram stretch does not actually require you to calculate the full histogram. The scaling factor
// is calculated from the minimum and maximum values in the image.
KMEANS Trains a k means cluster model.CENTRES = KMEANS(CENTRES, DATA, OPTIONS) uses the batch K-means
algorithm to set the centres of a cluster model. The matrix DATA
represents the data which is being clustered, with each row
corresponding to a vector. The sum of squares error function is used.
The point at which a local minimum is achieved is returned as
CENTRES.
Hybrid Monte Carlo sampling.SAMPLES = HMC(F, X, OPTIONS, GRADF) uses a hybrid Monte Carlo
algorithm to sample from the distribution P ~ EXP(-F), where F is the
first argument to HMC. The Markov chain starts at the point X, and
the function GRADF is the gradient of the `energy function F.

"The traveling salesman problem, or TSP for short, is this: given a finite number of cities along with the cost of travel between each pair of them, find the cheapest way of visiting all the cities and returning to your starting point."
New training algorithm for linear classification SVMs that can be much faster than SVMlight for large datasets. It also lets you direcly optimize multivariate performance measures like F1-Score, ROC-Area, and the Precision/Recall Break-Even Point.
“手機銀行”也稱為移動銀行，它是通過移動通信網絡將客戶的手機連接至銀行，實現利用手機界面完成各種金融理財業務的服務系統。“手機銀行”服務的推出，使得手機不再只是一個通信工具，還能進行金融理財，同時也成為了一個移動POS(point of sales)機，使其成為繼銀行柜臺、自助銀行、電話銀行、網上銀行之后的新的服務渠道。
Welcome to Beginning Algorithms, a step-by-step introduction to computing algorithms for the real world.
Developers use algorithms and data structures every day of their working lives. Having a good understanding
of these algorithms and knowledge of when to apply them is essential to producing software
that not only works correctly, but also performs efficiently.
This book aims to explain those algorithms and data structures most commonly encountered in day-today
software development, while remaining at all times practical, concise, and to the point, with little or
no verbiage to distract from the core concepts and examples.
AppWizard has created this DigitRec application for you. This application
not only demonstrates the basics of using the Microsoft Foundation classes
but is also a starting point for writing your application.
This demonstration models a flight control for the longitudinal motion of a Grumman Aerospace F-14 Tomcat. First order linear
approximations of the aircraft and actuator behavior are connected to an analog flight control design that uses the pilot s
stick pitch command as the set point for the aircraft s pitch attitude and uses aircraft pitch angle and pitch rate to determine commands. A simplified Dryden wind gust model is incorporated to perturb the system.
