摘要
针对大幅面待检测印刷品的检测中测量宽度与分辨率的矛盾,提出一种基于提升小波的选择性图像融合算法,对多线阵CCD并行采集的待检测印刷品图像信息进行融合。首先采用相应算法对图像是否需要融合进行判定;然后采用基于提升小波的图像融合算法进行图像融合。实验表明:该算法计算量明显减少,实时性明显提高,可满足大幅面印刷品在线检测的要求。
A lifting wavelet-based selective image fusion algorithm is put forward for the fusion of image information of printed matters parallel-acquired with multi-line array CCD,in order to resolve the conflict between the measuring width and resolution of large-format printed matters.Firstly,the necessity of image fusion is judged by adopting corresponding algorithms.Then,image fusion is carried out by using the lifting wavelet-based selective image fusion algorithm.Finally,experiments show that computation amount of this algorithm has been reduced greatly and its real-time performance has been improved significantly,so this new method may meet online inspection requirement of in large-format printing.
