  • 印刷电路板的图像分解去噪算法

      资源简介:为了改善印刷电路板(PCB)图像的视觉效果,提出基于图像分解的自适应加权L1范数和L2范数的PCB图像去噪算法。首先,将PCB噪声图像分解为结构和纹理两部分,其次设计一个自适应加权L1-L2范数正则化去噪模型。由于结构部分主要是分片平滑区域,体现PCB图像的整体框架,适合用L2范数各向同性去噪模型。纹理部分主要是高频信息,体现PCB图像的细节特征,适合用L1范数各向异性扩散正则化去噪模型。针对结构和纹理两个不同部分,设计自适应权函数,自动调整L1-L2范数正则化去噪模型中L1范数和L2范数的权值,然后,利用Bregman迭代算法得到最优的去噪效果。实验结果表明:与近年以来的相关经典去噪算法相比,利用新算法所得去噪图像的主观视觉效果更好,客观评价指标中的结构相似度可以提高27%以上,信噪比可以提高1 dB以上。In order to improve the visual effect of printed circuit board (PCB) images, a PCB image denoising algorithm based on weighted L1 norm and L2 norm is proposed. Firstly, the PCB noise image is decomposed into two parts of structure and texture by using the non local mean image decomposition method. Secondly, a denoising model based on L1-L2 norm regularization is designed. The structure part embodies the whole frame of PCB image, which is mainly a piecewise smooth region. Therefore, the L2 norm isotropic diffusion regularization denoising model based on the high weight value is used to denoise it.The texture part embodies the detail features of PCB images, corresponds the high frequency information, so the L1 norm anisotropic diffusion regularization denoising model based on high weight is adopted to denoise it. Then, the Bregman iterative algorithm is applied to get the best denoising effect. The experimental results show that compared with the classical denoising algorithm in recent years, the subjective visual effect of the denoised image obtained by the new algorithm is better, and the objective evaluation indexes, such as the signal to noise ratio and the structure similarity, are also improved accordingly.
