【摘要】 模糊图像复原的关键是估算它的点扩散函数。因为点扩散函数无法精确得到,所以无法获得模糊过程的精确模型。针对这一特性,研究了一种图像盲复原的方法,即在图像模糊过程的信息全部或部分未知的情况下,通过模糊图像的特征来估计真实图像和模糊算子。仿真试验表明了算法的有效性。更多还原

【Abstract】 The key to restore the blurred image is to estimate the Point Spread Function(PSF).It is difficult to ascertain the PSF,so the accurate model of the blurred process can not be got.Because of this characteristic, an algorithm about blind restoration of blurred image has been studied in this paper.It is on the condition that the information of the blurred process is unknown,the true image and blurred operators can be estimated by the characteristics of the blurred image.Final experiments are presented to demonstrate the effectiveness of the algorithm.更多还原
