Mathematica's symbolic architecture makes it possible to treat images just like any other form of expression—applying functions to them, displaying and inputting them in notebooks, and including them directly in programs.
Mathematica provides a streamlined collection of functions for basic image manipulation, fully integrated with more advanced processing and its overall language and interactive capabilities.
ImageCrop — crop to a given size, or remove boundaries
ImageTrim — remove the boundaries to include specified pixels
ImagePad — pad an image using various possible methods
ImageTake — take rows and columns of pixels in an image
BorderDimensions — use various methods to find borders on an image
ImageResize — resize an image by resampling its raster
ImageAdjust — adjust levels, brightness, contrast, gamma, etc.
ImageClip — clip pixel values
ImageEffect — special image and photographic effects
AlphaChannel — the alpha channel of an image
ImageCompose — alpha compositing
ImageData — extract the raw data array for an image
Image — create an image from a data array
