Spatial Transformations


This section describes the spatial transformation functions in the Image Processing Toolbox. Spatial transformations map pixel locations in an input image to new locations in an output image. Topics covered include
Terminology
Provides definitions of image processing terms used in this section
Interpolation
Defines interpolation, the process used to estimate the value of a pixel in an output image when that pixel does not appear in the input image
Image Resizing
Describes how to use the imresize function to change the size of an image
Image Rotation
Describes how to use the imrotate function to rotate an image
Image Cropping
Describes how to use the imcrop function to extract a rectangular portion of an image
Performing General Spatial Transformations
Describes the general spatial transformation capabilities of the toolbox
