标题： Rephotography in the Digital Era: Mass Rephotography and re.photos, the Web Portal for Rephotography

摘要： 自19世纪中叶开始重新摄影以来，重新摄影的登记、保护、展示和共享技术已经取得了长足的进步。 在这里，我们将介绍现有的数字重新摄影方法，并讨论数字大规模重新摄影的未来方法和要求。 我们介绍了re.photos，一个现有的重新摄影网络门户，具有协作重新摄影的方法、交互式图像登记，以及重新摄影的检索、组织和共享功能。 对于大规模重新摄影，必须满足额外的要求。 必须同时处理模板图像和重新摄影图像，图像登记必须自动化，并且必须提供直观的智能手机应用用于重新摄影。 长期存储带有持久标识符、自动或大规模地理参考，以及游戏化和社会媒体集成是本文将讨论的进一步要求。 显示英文摘要

摘要： Since the beginning of rephotography in the middle of the 19th century, techniques in registration, conservation, presentation, and sharing of rephotographs have come a long way. Here, we will present existing digital approaches to rephotography and discuss future approaches and requirements for digital mass rephotography. We present re.photos, an existing web portal for rephotography, featuring methods for collaborative rephotography, interactive image registration, as well as retrieval, organization, and sharing of rephotographs. For mass rephotography additional requirements must be met. Batches of template images and rephotographs must be handled simultaneously, image registration must be automated, and intuitive smartphone apps for rephotography must be available. Long--term storage with persistent identifiers, automatic or mass georeferencing, as well as gamification and social media integration are further requirements we will discuss in this paper.
