A subfield of digital image processing is binary image processing. Some algorithms applied in this field are classified as morphological image processing

A related field is computer vision, in which more abstract information is extracted from images. An example computer vision problem is acquiring a 3D of an environment from video footage of it. As part of such an algorithm, image processing techniques such as noise reduction and edge detection might be performed.

Some applications are:

• Satellite image processing
• Medical image processing
• Face detection, feature detection, face identification
• Microscope image processing
