IMAGE PROCESSING

'Image processing' is any form of information processing for which the input is an image, such as photographs or frames of video; the output is not necessarily an image, but can be for instance a set of features of the image. Most image-processing techniques involve treating the image as a two-dimensional signal and applying standard signal-processing techniques to it.

Typical operations

Among many other image processing operations are:

★ Geometric transformations such as enlargement, reduction, and rotation

★ Color corrections such as brightness and contrast adjustments, quantization, or conversion to a different color space

★ Registration (or alignment) of two or more images

★ Combination of two or more images, e.g. into an average, blend, difference, or image composite

★ Interpolation, demosaicing, and recovery of a full image from a RAW image format like a Bayer filter pattern

★ Segmentation of the image into regions

★ Image editing and digital retouching

★ Extending dynamic range by combining differently exposed images (generalized signal averaging of Wyckoff sets)

★ Image restoration to increase the quality of a digital image, such as deconvolution to reduce blur, restoration of faded color, removal of scratches, etc.
Besides static two-dimensional images, the field also covers the processing of time-varying signals such as video and the output of tomographic equipment. Some techniques, such as morphological image processing, are specific to binary or grayscale images.
