Abstract
This paper presents a new method of identification and restoration of images with out-of-focus blurs. The basic idea of the method is as follows: first use the gradient image of the blur image being processed to estimate the initial value of blur radius; then use the least square restoration technique and the Fibonacci optimal search technique to determine the blur radius. The experimental results with artificially and true defocused images showed that the present method is successful.
