最优找缝是一种常用的全景图构造策略。它具有快速构建全景图和节省内存的优点。然而,它本质上对辐射失真很敏感,这就是为什么在合成全景中经常可以看到伪影的原因。此外,它需要用户指定权重参数,这使得这种算法难以配置。本文充分利用相机模型,利用张量分析的知识,提出了一种新的最优寻缝方法。它不仅可以从扭曲的输入图像中创建无伪影的全景,而且不需要用户指定权重。我们通过对具有不同类型光学畸变的杂色图像集进行测试来验证我们方法的有效性。
Optimal seam finding is a popular panorama construction strategy. It has the advantage of constructing panorama rapidly as well as being memory efficient. However, it is intrinsically sensitive to radiometric distortions, which is why artifacts are often visible in the composed panorama. Besides, it requires users to specify weight parameters, making such algorithms difficult to configure. In this paper, by fully exploiting the camera model and utilizing the knowledge of tensor analysis, we propose a novel optimal seam finding method. It not only enables the creation of artifact-free panorama from distorted input images but also requires no user-specified weights. We verify the effectiveness of our method by testing it on variegated sets of images with different types of optical distortions.
