New in 7.0: Data Manipulation
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
ImageFilter apply an arbitrary filter to an image
Dilation, Erosion, ... — morphological transformations of 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
Median, Quartiles, QuartileDeviation, ... (modified) — use with symbolic distribution
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

New Import & Export Formats
GeoPosition geodetic position specified by latitude, longitude
GeoDistance distance between geodetic positions
GeodesyData, GeoProjectionData reference ellipsoids, datums and projections
