Probabilistic Graphical Model and Its Application in Image and Video Information Processing

Probabilistic graphical model(PGM) and its application have become a new hot-spot as a challenging research. It provides an important means for resolving the uncertainty of intelligent information field. Although PGM is still in its development, the application of intelligent information processing of images and videos based on PGM has emerged and many effective algorithms has emerged which provide a new strategy to solve for the traditional problems. Based on the three important expressions, the characteristics and the main technology of PGM,we analyze and introduce the primary technology of intelligent information processing of images and videos based on PGM. Finally, we discuss the disadvantages and development trend of PGM.
