- Image processing
Image processing is any form of
signal processingfor which the input is an image, such as photographs or frames of video; the output of image processing can 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 are also possible. This article is about general techniques that apply to all of them.
Among many other image processing operations are:
* Geometric transformations such as enlargement, reduction, and rotation
Colorcorrections such as brightness and contrast adjustments, quantization, or conversion to a different color space
Digital compositingor optical compositing(combination of two or more images). Used in filmmaking to make a "matte"
demosaicing, and recovery of a full image from a raw image formatusing a Bayer filterpattern
Image editing(e.g., to increase the quality of a digital image)
Image registration(alignment of two or more images)
* Image segmentation
* Extending dynamic range by combining differently exposed images
* 2-D object recognition with affine invariance
* Feature detection
