相机阵列多视角图像盲去模糊方法

Multi-view Blind Deconvolution Method of Camera Array System

  • 摘要: 提出了一种基于正则化方法的多视角盲去模糊方法,对相机阵列拍摄的一系列初始模糊图像进行图像恢复处理.该方法分为3个步骤:首先,基于光流算法对多个镜头获取的同一场景图像进行配准;然后,将配准图像运用多图盲去模糊算法估计出各自的模糊核;最后,根据估计出的模糊核采用非盲去模糊算法准确估计出各自的清晰图像.实验结果表明:相比对每一视角图像单独使用单图盲去模糊算法进行处理,多视角盲去模糊方法对噪声具有良好的鲁棒性;应用于自己构建的相机阵列系统拍摄的多视角图像,该方法在2种无参考图像指标NIQE和SSEQ下分别提高了4.20%和55.60%.

     

    Abstract: we proposed a regularization-based multi-view blind deconvolution method to complete image restoration of blurred images,which are captured by camera array system. This method is conducted with three procedures: firstly, an optical flow algorithm is utilized torealize the registration of adjacent images. Secondly, we use a multichannel blind deconvolution algorithm to estimate the blurs of eachinput blurred images after registration. Finally, according to the estimated blurs, clear images are obtained using non-blind deconvolutionalgorithm. Experiments show that, compared with single image blind deconvolution algorithm, the proposed method is robust to noise.When dealing with the blurred images captured by a camera array system constructed by ourselves, it performs better in terms of NIQE andSSEQ by 4.20% and 55.60% respectively.
