Résumé
The medical tasks in ImageCLEF have been run every year from 2004-
2018 and many different tasks and data sets have been used over these years. The
created resources are being used by many researchers well beyond the actual evaluation
campaigns and are allowing to compare the performance of many techniques on
the same grounds and in a reproducible way. Many of the larger data sets are from
the medical literature, as such images are easier to obtain and to share than clinical
data, which was used in a few smaller ImageCLEF challenges that are specifically
marked with the disease type and anatomic region. This chapter describes the main
results of the various tasks over the years, including data, participants, types of tasks
evaluated and also the lessons learned in organizing such tasks for the scientific
community.
