Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that a linear map g from V to V is well defined by the equation () = (); here, as usual, the subtraction of two points denotes the free vector from the second point to the first one, and "well-defined" means that ...

The Harris affine detector can identify similar regions between images that are related through affine transformations and have different illuminations. These affine-invariant detectors should be capable of identifying similar regions in images taken from different viewpoints that are related by a simple geometric transformation: scaling, rotation and shearing.
Affine motion estimation is a technique used in computer vision and image processing to estimate the motion between two images or frames. It assumes that the motion can be modeled as an affine transformation (translation + rotation + zooming), which is a linear transformation followed by a translation.
Digital image processing is the use of a digital ... can be reduced to a single affine transformation matrix. For example, ... software; Standard test image;
Each identified cluster is then subject to a verification procedure in which a linear least squares solution is performed for the parameters of the affine transformation relating the model to the image. The affine transformation of a model point [x y] T to an image point [u v] T can be written as below

Inkscape supports image tracing, the process of extracting vector graphics from raster sources. Clones are child objects of an original parent object. Different transformations can be applied to them, such as: size, position, rotation, blur, opacity, color and symmetry. Clones are updated live whenever the parent object changes.
