Evaluation Data for Virtual Multistaining Registration

Comparative evaluation of registration methods applied to histology data is difficult due to the lack of ground truth data in most datasets. We provide annotated histology data of multiple stains that can be used for registration. The accuracy of the registration can be evaluated based on corresponding structures that have been segmented manually.

Data description

The image data is available as Hamamatsu (ndpi) files and annotations are available as point lists in a sqlite-database format. A sample python file is provided to access the annotations.


We manually segmented between five and twelve structures in each image. The points of the segmentations are stored in files annotations/[image_file_name].sqlite. The simplest way to access this data is by using the sample python file provied. You may limit the x- and y- ranges to only select a specific structures. Currently, the individual structures can not be separated solely based on the sqlite data (we are working on it).
