Pre-processing of Face Image Recognition in Driver Forewarning System

Driver Forewarning System is most important for improving vehicle traveling safety,and driver's face image recognition is the key part of the Driver Forewarning System.The principle framework of Driver Forewarning System is introduced firstly.Then two sections of pre-processing,namely the filtering and making thinner are discussed.By using KARLMAN filter algorithm,the colorful noise is filtered,and the target tracking is realized at the same time.By using elimination shell algorithm to make the image thin,the line description is made.These work provides a credible guarantee for succedent driver's face image recognition,and experiment shows that the method described in this paper is with real time and good effect iveness.
