The 2020 International Joint Conference on Biometrics (IJCB 2020) combines two major biometrics research conferences, the Biometrics Theory, Applications and Systems (BTAS) conference and the International Conference on Biometrics (ICB). The blending of these two conferences in 2020 is through a special agreement between the IEEE Biometrics Council and the IAPR TC-4, and should present an exciting event for the entire worldwide biometrics research community.
