Implementation Of 4D Face Image Database

With the development of computer technology,such as face recognition technology has also obtained the development and application in many fields,and face image database is the foundation of the technology research such as face recognition,development and research of all kinds of algorithm needs a good face image database.In this paper,it is in this demand under the design of the face image database,hope that through this after a database for face recognition technology research and development provides a new platform.In this paper,on the basis of previous face image database design to join the time dimension,the time dimension mainly includes the following aspects,one is face image acquisition time,2 it is image processing system time,3 it is through the face image face is used to estimate the age of time,four is the background of the image season.Through the database design,can put the physiological age and time of the body and the information of the face image to connect.Therefore set up four dimensional human face image database for later processing time dependent human face image.This paper detailed introduces the related technology parameters and time regarding the handling of face image acquisition method.Mainly of face image layers of processing,the first is in face of face image after image preprocessing,and then the face region from the face image segmentation,finally features shown in segmentation of face region after separation.This progressive layers can make our final data obtained from the more true and accurate.To obtain time parameters are divided into the following several ways: one is known to be the photographer's age accurately,as well as the image acquisition time;Second,don't know the photographed a precise age,but there are accurate image taken;Age,and the image of the three is the photographed accurately acquisition time all don't know.For two,three,two kinds of circumstances,can be estimated by image processing face season in age and background.At the same time also introduces the relevant database creation theory,and analysis of the data table and argument,so that they meet the requirements of each paradigm.Through the introduction to several modules achieve of 4d face image database.
