Image Filtering & Neighborhood Processing
Mathematica not only includes highly optimized implementations of standard image processing filters, but also uses its general symbolic architecture to allow arbitrarily sophisticated filtering and neighborhood processing strategies to be set up using the full mathematical and algorithmic power of Mathematica.
Linear Filters
Blur, Sharpen blur, sharpen over a range
GaussianFilter Gaussian and Gaussian derivatives filter
ImageConvolve, ImageCorrelate general linear convolution, correlation
Nonlinear Filters
General Neighborhood Processing
ImageFilter apply an arbitrary function to blocks of pixel values
