This paper presents an efficient optimized backlight local dimming method that minimizes power consumption under a given allowable distortion for liquid crystal displays with edge-lit light-emitting diode backlight. To reduce image quality fluctuation, an inequality constraint optimization problem is formulated using a given allowable distortion and the steepest descent method is used to solve the...
Several techniques using technology based on biometrics, passwords, certificates, and smart cards can be used for user authentication in the accessible network system. One of the most popular areas in OTP authentication protocol can be used for authenticating a user by a server. It increases security by using a new password for each authentication while the previous password scheme iteratively uses...
