Blur Identification and Restoration of Images with Out-of-Focus Blur
离焦图象模糊辨识及复原方法研究

In this paper, the problem of determining the model parameters of the degraded image and restoring the image from a defocused blur image is studied. An efficient method based on the gradient image of the blur image, least square restoration technique and Fibonacci optimal search method is presented. The basic principle of the method and the algorithm for the method are discussed. The experimental results are given in the paper.
