许多图书馆和博物馆采用了国际图像互操作性框架（IIIF），以促进不同机构之间的图像互用。在IIIF兼容的数字集合中，经由IIIF图像API（应用编程接口）检索图像，其中可以指定图像的区域。因此，可以通过检查已被请求的图像区域来详细调查图像使用。在这篇文章中，我们提出了一个日志分析方法来衡量图像的使用和可视化的分析结果。具体来说，我们使用访问每个像素的次数，并使用热图将结果可视化。考虑到像素是最小的图像单元，我们在此应用细粒度分析。该分析方法可以用于不同的应用，包括研究人员检查图像的研究工具和显示图像的哪些区域已经被合作者检查过的热图。
Numerous libraries and museums have adopted the International Image Interoperability Framework (IIIF) that promotes mutual use of images among different institutions. In a IIIF-compatible digital collection, images are retrieved via IIIF Image API (Application Programming Interface), wherein regions of images can be specified. Thus, it is possible to investigate image usage in detail by examining the image regions that have been requested. In this article, we propose a log analysis method to measure the image usage and to visualize the analysis outcomes. Specifically, we employ the number of accesses to each pixel and visualize the results using heat maps. Given that a pixel is the smallest image unit, we apply herein a fine-grained analysis. The analysis method can be used in different applications including research tools in which researchers examine images and heat maps that show which regions of the images have already been examined by collaborators.
