摘要 提出一种基于高频图像L1范数的模糊图像复原算法。该算法分为两个步骤:估计模糊图像的模糊函数和去卷积复原图像。在模糊函数估计中,利用梯度算子计算模糊图像的高频图像,并构建此高频图像的L1范数作为代价函数正则化项,使得代价函数能在最小化时达到优化,有利于模糊函数的估计;估计出模糊函数后,采用一种具有抗模糊函数估计误差的泛函优化算法对图像进行去卷积处理,对模糊图像进行复原。 This paper proposes an image restoration algorithm based on L1 norm of the high frequency image as regu- larization.A functional optimization algorithm,robust to errors of the blur function,is adopted in de-convolution processing in order to restore the original sharpen image from its blurry one.
