Category:Image processing - 123SeminarsOnly

In
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. Most image
-
processing techniques involve treating the image as a
two
-
dimensional

signal

and applying standard signal
-
processing techniques to it.

Image processing usually refers to
digital image processing
, but
optical

and
analog image
processing

also are possible. This article is about general techniques that apply to all of them.
The
acquisition

of images (producing the input image in the first place) is referred to as
imaging
.

==Typical operations==operation



The red, green, and bl
ue color channels of a photograph by

Gorskii
, the fourth image is a composite




Euclidean geometry transformations

such as
enlargement
, reduction, and
rotation



Color corrections such as
brightness

and
contrast

adjustments,
color mapping
,
color
balancing
,
quantization
, or
color translation

to a different
color space



Digital compositing

or optical
com
positing

(combination of two or more images), which
is used in film
-
making to make a "
matte

, and recovery of a full image from a
raw image format

using a
Bayer fi
lter

pattern



Image registration
, the alignment of two or more images



rencing

and
morphing

Image processing

is the application of
signal processing

techniques to the domain of
images

—

two
-
dimensional
signals

such as
photographs

or
video
. Image processing does typically involve
filtering

an image using various types of filters.
