N-jet
Encyclopedia
An N-jet is the set of derivatives of a function 
up to order 
.
Specifically, in the area of computer vision
, the N-jet is usually computed from a scale-space representation
of the input image 
, and the partial derivatives of 
are used as a basis for expressing various types of visual modules. For example, algorithms for tasks such as feature detection, feature classification, stereo matching, tracking and object recognition can be expressed in terms of N-jets computed at one or several scales in scale space.

Computer vision
Computer vision is a field that includes methods for acquiring, processing, analysing, and understanding images and, in general, high-dimensional data from the real world in order to produce numerical or symbolic information, e.g., in the forms of decisions...
