based on an earlier version of the Wolfram Language.
Building on Mathematica's unified symbolic architecture, Mathematica 7 introduces several major new integrated forms of data manipulation—including large-scale support for images, for statistical models, and for geodetic data.
Image — create an image from an array of data, and represent any multichannel image
ImageAdjust — adjust levels, brightness, contrast, gamma, etc.
ImageFilter — apply an arbitrary filter to an image
LinearModelFit — construct a linear regression model from data
NonlinearModelFit — construct a nonlinear regression model
DesignMatrix — construct a design matrix from data
Standardize — shift and rescale the data to zero mean and unit variance
BezierFunction — create a function representing a Bézier manifold in any dimension
BSplineFunction — create a function representing a B-spline manifold in any dimension
Interpolation (modified) — find interpolation at a point
GeoPosition — geodetic position specified by latitude, longitude
GeoDistance — distance between geodetic positions
