Paper Abstract

A novel approach is proposed to estimate the parameters of rotational motion blur. Firstly, the rotational blur was changed into translational motion blur by geometric transformation from Cartesian coordinate system to polar coordinate system. The characteristic of the translational motion blurred image in frequency domain was concluded. Then, the characteristic was further analyzed by a new definition of point spread function (PSF). Based on this, an object function was derived to describe the relationship between the parameter and the characteristic. At last, the statistical optimal parameter of the blur motion was obtained by traversing through the resolution space of the object function. The comparing experiment results demonstrate that the new method has better accuracy than traditional ones.
