Digital image processing

Digital image processing is the study of algorithms applied to digital images. Typical problems covered by this field include

and many more.

Besides static two-dimensional images, the field also covers the processing of three-dimensional signals such as digital video and the output of tomographic equipment. Some techniques, such as morphological image processing, are specific to binary or grayscale images.

The name 'image processing' is most appropriate when both inputs and outputs are images. The extraction of arbitrary information from images is the domain of image analysis, which includes pattern recognition when the patterns to be identified are in images. In computer vision one seeks to extract more abstract information, such as the 3D description of a scene from video footage of it. The tools and concepts of image processing are also relevant to image synthesis from more abstract models, which is a major branch of computer graphics.

Some applications are:
