JPEGs are compressed using the discrete transform of this name, which separates the image pixels into bands of similar importance.  
JPEGs are compressed using the discrete transform of this name, which separates the image pixels into bands of similar importance.  A correlation representing this function, also known as uncentered correlation, is used in pattern recognition and information retrieval to determine the similarity of two feature vectors via a normalized dot product. Its hyperbolic form describes the shape of a catenary, and for two vectors of unit length, taking a dot product will give you this function of the angle between them.  The reciprocal of the secant function, FTP, name this trigonometric function, which, for an angle in a right triangle, equals the ratio between the adjacent side and the hypotenuse.
