Cloud-based platform for human-in-the-loop re-annotation of whole slide imaging: large scale semantic pathology segmentation

In our previous work, we have demonstrated that it is possible to use a small bootstrap set of fully annotated regions of interest (ROIs) to generate segmentation results on the WSI scale. In this work, pathologists were asked to edit the previously generated annotations on 150 WSIs, focusing on only the tumor class. Of these re-annotated WSIs, 21 were then sampled from, and used to train a new version of the classifier. Segmentation results were then generated for the remainder of the images. This work demonstrates an improvement in segmentation of the tumor class.
