Potential Contrast: Properties, Equivalences, and Generalization to Multiple Classes

Authors:Wallace Peaslee, Anna Breger, Carola-Bibiane Schönlieb

Potential contrast is typically used as an image quality measure and quantifies the maximal possible contrast between samples from two classes of pixels in an image after an arbitrary grayscale transformation. It has been valuable in cultural heritage applications, identifying and visualizing relevant information in multispectral images while requiring a small number of pixels to be manually sampled. In this work, we introduce a normalized version of potential contrast that removes dependence on image format and also prove equalities that enable generalization to more than two classes and to continuous settings. Finally, we exemplify the utility of multi-class normalized potential contrast through an application to a medieval music manuscript with visible bleedthrough from the back page. We share our implementations, based on both original algorithms and our new equalities, including generalization to multiple classes, at https://github.com/wallacepeaslee/Multiple-Class-Normalized-Potential-Contrast.

潜在对比度通常被用作图像质量的一种度量标准,它量化了在任意灰度变换后,图像中两个类别的像素样本之间的最大可能对比度。它在文化遗产应用领域中具有价值,能够在多光谱图像中识别和可视化相关信息,同时只需要少量像素进行手动采样。在这项工作中,我们介绍了潜在对比度的归一化版本,该版本消除了对图像格式的依赖,并证明了等式,使我们可以将其推广到多于两个类别和连续设置的情况。最后,我们通过中世纪音乐手稿的一个应用示例展示了多类归一化潜在对比度在可见背透页面上的实用性。我们分享了基于原始算法和新等式实现的方法,包括推广到多个类别的实现,详情链接为:https://github.com/wallacepeaslee/Multiple-Class-Normalized-Potential-Contrast。
