Image analysis typically utilizes mathematical models in conjunction with image processing techniques to analyze underlying features and overlying structures to extract information with some intelligence.

The mode recognition and artificial intelligence method is also called scene analysis or image understanding. Since the 60's of the 20 th century, there have been many studies on image analysis, and the development of image analysis techniques for specific problems and applications has gradually moved toward the establishment of general theories. The image analysis is closely related to the research content of image processing, computer graphics and the like, and is mutually crossed and overlapped.
