多约束的运动模糊图像盲复原方法
Multi-constraint Blind Restoration Method for Motion Blurred Image
摘要
Abstract
Blind restoration of a motion-blurred image is a long-standing and challenging inverse problem. In order to estimate motion blur kernel (MBK) accurately and obtain a high-quality restoration image, a regularization-based multi-constraint blind restoration method for motion-blurred images is proposed. First, in order to extract the large-scale edges from the image accurately, a sparse image smoothing method, based on gradient selection, is proposed. Then, in the MBK estimation step, based on the inherent properties of the MBK, a multi-constraint regularization model, which combines the extracted large-scale image edges, is proposed. Finally, the multi-constraint regularization model, which is proposed in the MBK estimation step, is addressed by using a half-quadratic variable splitting scheme. Extensive experiments are performed on both synthetic blurred images and real-life blurred images. Experimental results indicate that in comparison with several recent successful representative image blind restoration methods, the proposed method is an improvement not only in terms of subjective vision, but also in terms of objective numerical measurement.关键词
