electrical engineering and computer science, image processing
is any form of signal processing for which the input is an
image, such as a photograph or video frame; the output of
image processing may be either an image or, a set of characteristics
or parameters related to the image.
of Image processing
vision is the science and technology of machines that
see, where see in
this case means that the machine is able to extract
information from an image that
is necessary to solve some task.

land-based vehicle. Notice the stereo cameras mounted
on top of the Rover.

In its simplest operation, a machine will simply see
how much light is reflected off the object using a simple
Photodetector (such as a Photoresistor) and accept or
reject the item depending of how reflective it is (light
reality (AR) is a term for a live direct or indirect
view of a physical real-world environment
whose elements are augmented by virtual computer-generated
is related to a more general concept called mediated
reality in which a view of reality is modified (possibly
even diminished rather than augmented) by a computer.

detection is a computer technology that determines the
locations and sizes
of human faces in arbitrary (digital)
images. It detects facial features and ignores anything
else, such as buildings, trees and bodies.

computer vision and image processing the concept of
feature detection refers to methods that aim at computing
abstractions of image information and making local decisions
at every image point whether there is an image feature
of a given type at that point or not.
The resulting features will be subsets of the image
domain, often in the form of isolated points, continuous
curves or connected regions.

departure warning system
a lane departure warning system is a mechanism designed
to warn a driver when the vehicle begins to move out
of its lane (unless a turn signal is on in that direction)
on freeways and arterial roads.
These systems are designed to minimize accidents by
addressing the main causes of collisions: driving error,
distraction and drowsiness.

rendering (NPR) is an area of computer graphics that
focuses on enabling a wide variety of expressive styles
for digital art.
contrast to traditional computer
graphics, which has focused on
photorealism, NPR is inspired by artistic styles such

imaging is the technique and process used to create
images of the human body (or parts
and function thereof) for clinical purposes (medical
procedures seeking to reveal, diagnose or examine disease)
or medical science (including the study of normal anatomy
Although imaging of removed organs and tissues can be
performed for medical reasons, such procedures are not
usually referred to as medical imaging, but rather are
a part of pathology.

image processing is a broad term that covers the use
of digital image processing techniques to process, analyze
and present images obtained from a microscope.
Such processing is now commonplace in a number of diverse
fields such as medicine, biological research, cancer
research, drug testing, metallurgy, etc.
Morphological image processing
morphology (MM) is a theory and technique for the analysis
of geometrical structures, based on set theory, lattice
theory, topology, and random functions.
MM is most commonly applied to digital images, but it
can be employed as well on graphs, surface meshes, solids,
and many other spatial structures.

sensing is the small- or large-scale acquisition of
information of an object or phenomenon, by the use of
either recording or real-time
sensing device(s) that are wireless,
or not in physical or intimate contact with the object
