Steering kernel-based Richardson-Lucy algorithm and its application in image restoration
Wang Qia · Journal of Northeast Normal University · 2014
This paper will propose a new image restoration method for the blurred noisy image.It combines Richardson-Lucy algorithm with steering-kernel.This method uses steering-kernel to contain the noise of the blurred noisy image firstly,which improving the signal-to-noise ratio of the image,and then use Richardson-Lucy algorithm to recover the blurred noisy image.This method can overcome the noise amplification problem that caused by the repeated iteration when this paper make use of the Richardson-Lucy algorithm merely,and has been verified by experiments that this method can improve the recovery effect significantly.
