摘要
A new method of calculating ene optical transfer function (OTF) for image blur caused by arbitrary motion is introduced. Previous methods, except for a few specific types of motion, were numerical rather than analytical. This new method makes it possible to obtain analytical expressions for the OTF deriving from any kind of motion by means of the statistical moments of the motion function. Analytical OTF expressions are derived age degradation is presented for linear and exponential motion and high-frequency vibration of the same blur extent. The method can be implemented in real-time restoration of images blurred by arbitrary motion and in image motion degradation analysis. (C) 1997 Optical Society of America [S0740-3232(97)01602-5]
